(120°C). All plates larger than 1" should be preheated between 400°F
and 600°F (205°C and 315°C) in order to avoid premature hardening
and cracking.
One of the greatest advantages of Astralloy-V, compared to other
wear steels, is that it can be hot formed and allowed to air cool
without losing its original properties. We recommend a minimum

When fabricating gears or sprockets, we recommend the material
be stress relieved between 500°F and 600°F (260°C – 315°C). Please
contact our technical department for more information.
Shearing is not recommended, as damage to shears may result from
Astralloy-V’s higher physical properties.
Drilling
Astralloy-V can be drilled with a high speed alloy or hardened bit.
The drill bit must be sharpened so that it has an angle of 140° to
150°, being careful to center the point of union between both sides.
The speed for cobalt drill bits should be 8 – 10 SFM and 4 – 6 SFM
Welding
In order to weld Astralloy-V, a fresh and dry electrode that is low
in Hydrogen is recommended. The E7018 is excellent for normal
welding procedures, providing adequate strength with good ductility.
In colder climates, it is always recommended that the plate be
preheated to over 300°F (149°C) to remove moisture. The preheating
should be applied to areas that will be welded and must uniformly
penetrate the full thickness of the plate. In cold temperatures or
moving air, insulate the weld to prevent rapid cooling.

Astralloy 8000 is an anti-abrasive, high-quality oil tempered steel. It is characterized by its
high performance, with resistance to wear 50% better than water tempered 500 BHN steels.
Astralloy 8000 features an innovative concept, based on an original combination of chemical
analysis and heat treatment (oil tempering). This combination gives the steel enhanced
resistance to abrasion by adding the following features:
* Fine chrome and molybdenum carbides that reinforce the steel’s microstructure.
* Exceptional added 70 BHN work hardening capacity, produced by a metallurgical process
called Transformation Induced Plasticity (TRIP).
Note: The data contained in this document is accurate at time of printing, and intended for use as a general guide.
*Typical maximum values. Chemical composition may vary by thickness. Mill certifications are available upon request.

CUTTING
* All the classic thermal cutting processes (oxy-plasma-laser) can
be used without preheating for thicknesses up to 1 ½" (the plate
temperature must be at least 50°F (10°C). Plates above 1 ½" thick
must be preheated to 302°F (150°C) to avoid fractures at the
edges. Plasma and laser processes are especially recommended
because they increase the precision and appearance of cuts and
limit alteration of the affected area.
* Water jet cutting can be used.
* Do not shear thin plates.

FORMING
* Cold forming or bending can be performed without difficulty, as
long as the following conditions are observed:
• Edges prepared by grinding to minimize imperfections
produced by oxycutting.
• Respect the minimum bend radius. The plate temperature
must be at least 50°F (10°C).

EB 450 is a liquid, quenched and tempered, through-hardened, high impact alloy steel
with excellent abrasion-resistant properties. Its balanced boron, modified nickel-chrome
moly chemistry is ideal for achieving an optimum hardness to toughness ratio. EB 450
boasts a longer wear life due to its through-hardness which is more uniform than what
is found in conventional carbon/manganese steels. This quench-hardened material is
competitively priced for optimum cost/wear rations. This steel’s resistance to atmospheric
corrosion further reduces surface pitting. EB 450 is field proven in extremely abrasive bulk
handling installations.

EB 450
BENEFITS
* Higher wear resistance, when compared to conventional steels,
due to its uniform hardness.
* Easy to weld with normal low hydrogen simple techniques.
* May be flame cut with oxyacetylene, plasma or similar methods.
* Cold formable with heavy presses or rolls.
* The high hardness and toughness in combination with its high
friction coefficient, reduces maintenance costs.
* EB 450 may be easily cut, welded, machined and cold formed,
as required.
To re-sharpen the tool, a point angle between 135° and 150° and
negative rake is recommended. Speed must be between 10 – 20
SFPM (surface feet per minute). For example, when drilling 3/4", the
feeding must be between 0.004" and 0.008" per revolution.
MANUFACTURING
Despite the high toughness of EB 450, it is possible to bend it
with a hydraulic press and cold form it. We recommend bending it
transverse to the rolling direction marked on each plate.
The internal minimum radius for forming EB 450 is:
The following parameters are provided as a guide:
* When bending transverse to the rolling direction, the minimum
radius is 6 times the thickness of the plate.
CUTTING
* When bending parallel to the rolling direction, the minimum
radius is 12 times the thickness of the plate.
The most common cutting methods for EB 450 plate are flame
and plasma. For a successful cut, use the procedures and fuel
recommended by equipment vendors.
* To cold bend the EB 450 plate to 90°, form in gradual steps
without exceeding the recommended minimum radius.
As a precaution, the EB 450 plates must be pre-heated before
WELDING
cutting. Thicknesses of up to 1" require a temperature of 250°F
The EB 450 is readily weldable by following some basic welding
(120°C) and larger thicknesses require a temperature of 300°F
guidelines.
(140°C).
Normally, for anti-abrasive applications, these cut methods provide
a precision range of +/- 1/8" along the length and width. For
applications where stricter tolerances are required, please consult
our technical department.
DRILLING
EB 450 requires slow speeds for better drilling. Feed speed must be
maintained constant.
To prevent cracking during the welding process, the following three
areas should be controlled:
1.Eliminate hydrogen pick-up in the weld metal during welding.
2.Minimize stress in the weld joint.
3.Use proper preheat and interpass temperatures and avoid rapid
cooling of the weld area following welding.
While welding the EB 450 product, we recommend the use of skip
welding and backstep welding procedures, as well as minimizing the
heat input.
For optimum drilling results, we recommend using low rpm speeds
for tools, short stem bits and generous cutting lubrication. Bits with
carbide inserts provide longer life; however, a good quality high
speed bit is enough.

AstraWear 500F is a water tempered martensitic steel, with 500 BHN (51.5 HRC), typical
hardness and resistant to wear from very severe abrasion. Its mechanical properties,
high wear resistance, hardness, and strength make AstraWear 500F steel ideal for use in
applications requiring resistance to sliding abrasion and where 400 BHN steels do not provide
a long enough service life.
Compared with conventional steels, like A572-50 (S355), AstraWear 500F offers real
improvement in equipment lifespans, of up to 5 times, and consequently allows for significant
reductions in design thickness.
AstraWear 500F steel is especially suited for applications in quarries, construction, mines,
cement plants, and the iron and steel industry, among others.

Metal: Astralloy Trip-L-Tuff has significant advantages in some areas
chemistry and properties as the plate overlay. It is applied to the

is not heat treated, so welding does not affect its properties. It can
be formed to a radius as small as 3" (on thin plate.) With the relaxed
condition of the Astralloy Trip-L-Tuff base material, the forming will
not create cracks on the outer bend, and with the consistency of the
Astralloy Trip-L-Tuff weld material,no spalling or breakage will occur
on the inner surface.
Base material is ASTM A 36 structural steel. The overlay consists of
predominantly hard chromium carbides in a tough iron-base matrix.
Nominal hardness is 555 – 653; microhardness of chromium carbide
is 1800 VPH (70 – 75 Rockwell C converted.)
Astralloy Trip-L-Tuff combines a super hard, tough surface on a ductile
and weldable mild steel backing to provide the ultimate wearresistant plate. Superior metallurgical properties achieved In a highly
controlled process utilizing the proper blend of elements result in an
overlay with an abundance of ultra-hard chromium carbide particles
evenly distributed in an extremely hard, tough matrix. These carbides
are 3 to 4 times as hard as steel as measured in microhardness tests.
Applications and Uses
Astralloy Trip-L-Tuff pipe is used primarily for wear due to friction.
With plate, this could be from coal, rock, or gravel moving through
or across a chute, liner, cyclone, sizing screen, dozier blade, breaker
plate, etc. With the pipe, applications may include slurry, coke, coal
dust, etc.
Advantages over other wear materials
Ceramic: Astralloy Trip-L-Tuff also has certain advantages over
ceramics. Given the high price of ceramics, cost is a major factor.
Installation costs are also a factor due to the thickness and
attachment procedures necessary for the fragile ceramic.
Chipping is another factor inherent in ceramic. Ceramic cannot
handle impact whatsoever, whereas the Astralloy Trip-L-Tuff will
handle moderate to (in some cases) severe impact. Attachment
failure is yet another drawback to glued on ceramic pieces. In piping,
Astralloy Trip-L-Tuff is particularly better suited than ceramic. Due to
the thickness of ceramics, special “odd-ball” mechanical tubing and

connections are no longer a concern.
Astralloy Trip-L-Tuff will typically exhibit stress relief cracks in the
overlay surface. These cracks are an inherent feature of hard-facing
and develop as the overlay cools following deposition, at 5/8" to 2"
spacing transverse to the weld bead. They are confined to the overlay
and do not penetrate into the base plate nor propagate in service.

CUTTING
* Plasma arc cutting is recommended for making holes, cutting
shapes, or beveling. Carbon air-arc method may be used for
gouging or non-precision holes. Cut from the mild steel side.
FORMING
* Astralloy Trip-L-Tuff can be formed by conventional shop
procedures. The overlay side must be on the inside of any formed
radii. Protect bending rolls with 3/16" plate over hard-faced sides.
MACHINING
* Electrical discharge machining (EDM) methods are used for
precision machining of Astralloy Trip-L-Tuff. Conventional
cutting tools, cermeis, and carbide will not cut Astralloy
Trip-L-Tuff.
* The hard chromium carbide overlay can be ground using a hard
grit wheel having a soft bond.

* Do not pre-heat.
* Remove rust, grease, organic and other foreign matter.
* Reduce energy input and heat buildup by maintaining a short arc,
minimizing puddling, and skip weld where possible.
* Inter-pass temperatures should not exceed 600°F.
* The following targets should be used as an initial setting:
7/64 flux cored wire (GMAW)
350 – 400 amps
5/32 covered electrode (SMAW)
140 amps
1/8 covered electrode (SMAW)
120 amps
* Minimize undercut of base metal. Limit the width of the weave to
four times the wire diameter.
* Use DCRP (reverse polarity).
* Multiple pass welding is recommended.
* Immediate peening of the red hot beads will reduce internal
stresses resulting from contraction during cooling.
* Do not post-heat.
The deeper layers maintain a ductile
structure capable of withstanding high
shock loads.
Electrodes for Welding Like Metals (Mn to Mn)
* Use austenitic manganese composite electrodes covered or
tubular with less than 0.025% phosphorus and greater than 14%
manganese. Several good proprietary rods are available. The
following are recommended:
Covered - McKay Hardalloy 118 - composite coated, low
phosphorus austenitic manganese 21% alloy steel.
Tubular - McKay Tube-Alloy 218-0. - low phosphorus
austenitic manganese 19.5% alloy steel.
Electrodes for Welding Dissimilar Metals (Mn to Mild Steel)
* Austenitic stainless steel- Type 308-16, 309-16, or 310-16 titania
coated, stainless steel electrodes can be used, but are more
expensive than manganese steel filler metals.
* For flux-cored arc welding with an auxiliary gas, the best results
are obtained when the shielding gas is 100% argon.
Storage of Electrodes
* Purchase low hydrogen electrodes in hermetically sealed
containers. Large containers may have electrodes with too much
moisture which can result in underbead cracking. Electrodes
which are exposed to air for over one hour should be baked in a
500°F ventilated oven for two hours.
* Use smallest applicable rod diameter to allow for full
penetration.

will develop a very high surface hardness.
Rol-Man
Drilling
Machining
* Rol-Man can be successfully drilled with “M-Style Hardsteel
Drills”. Hardsteel drilling is friction drilling, not twist drilling. The
process involves heating the steel under the drill point, not just
cutting it cold.
* On a lathe, use carbide tools, 90 – 100 SFM, feed at .012" per
revolution for roughing, and .008" revolution for finishing.
* For milling, use carbide tools, 50 SFM, with a .004- chip load per
insert per revolution.
* Maintain selected speed and constant feed pressure.
* Use rust-inhibited water coolant to minimize drill heating.
Cutting
* Because Rol-Man is a work hardening steel, conventional drill bits
tend to harden rather than cut the steel.
* Plasma or laser cutting works well. Oxyacetylene cutting gives a
poor edge.
* Set the spindle speed according to the table below:
* Shearing or punching on sturdy machines with property
sharpened edges is possible. However, this will work harden the
immediate area.

Forming
* Rol-Man forms much the same as mild steel of comparable
hardness.
* There is little work hardening in bending or rolling.
* Any previously work hardened areas, such as sheared edges or
drilled holes, should be ground away before bending stresses
are applied.
* A light beveling of edges is helpful. Preheating is unnecessary for
cold forming operations.

Astralloy-V round bars have the same chemistry, uniform toughness and hardness as plate,
from surface to core. Astralloy-V’s ultra-fine grain structure, free of massive carbide particles
due to its lower carbon content, provides better machinability at its higher strength/hardness
level than quenched and tempered alloys.
ADVANTAGES
* Maintains its toughness and hardness without brittleness at temperatures of up to -75°F.
* Uniform hardness throughout the mass (340 BHN) to resist abrasion.
* Hardenability in the range of 550 BHN by impact or sliding action, without deformation or
brittleness.
* Astralloy-V’s small oxide surface quickly disappears, exposing a slick, durable surface.
* Can be hot worked and allowed to air cool without loss of hardness or toughness and
without warpage problems.

MACHINING
For the best continuous machining, we recommend using disposable negative rake,
mechanically clamped tungsten carbide inserts and contoured grinders.
For an excellent finish, speeds should be 180 to 270 SFM. A generous and continuous
lubricant/coolant bath will prolong tool life.
For better metal removal, the cutting depth should exceed the feed rate by a factor of 10.
MILLING
For optimum metal removal in interrupted machining, use negative rake, mechanically
clamped tungsten carbide inserts. The generally recommended feed rate is 0.003" per tooth.
The total cutting rate is equal to 0.003" times the number of inserts in the cutter x rpm.
Uniform feed distribution requires the use of precision inserts.
At a hardness of 350 BHN, 150 surface feet per minute is reasonable. Slower rates for greater
hardness and higher rates for lesser hardness.

Welding
In order to weld Astralloy-V, a fresh and dry electrode that is low in Hydrogen is
recommended. The E7018 is excellent for normal welding procedures, providing adequate
strength with good ductility.
In colder climates, it is always recommended that the plate be preheated to over 300°F to
remove moisture. The preheating should be applied to areas that will be welded and must
uniformly penetrate the full thickness of the plate. In cold temperatures or moving air,
insulate the weld to prevent rapid cooling.
