The table provides an overview of the availability of various sheet steel grades from ArcelorMittal. These are available
as hot rolled or cold rolled steel substrates. Depending upon customer requirements, the cold rolled products are
available as bare or with a variety of corrosion protection coatings.
ArcelorMittal produces a full range of mild steels satisfying various customer forming requirements. These are
Commercial Steels (CS), Drawing or Forming Steels (DS or FS), Deep Drawing Steels (DDS), Extra Deep Drawing
Steels (EDDS) and Extra Deep Drawing Steels Plus (EDDS PLUS).
Dent Resistant Non-Bake-Hardening and Bake Hardening grades of steels are available from ArcelorMittal.
ArcelorMittal’s isotropic (ISODENT) dent resistant non-bake-hardening steel provides uniform mechanical properties
in all rolling directions. These steels are used for exposed quality autobody panels and unexposed quality structural
®
applications. ArcelorMittal’s MINDENT family of steels are available for dent resistant bake-hardening applications.
These grades are extensively used for exposed quality outer-body panel applications and for structural applications.
ArcelorMittal offers several steels ranging in yield strength grades from 180 MPa to 300 MPa.
Conventional high strength steels (HSS) are those that have been traditionally used by the automotive industry and
these include C-Mn grades and microalloyed grades termed as High Strength Low Alloy (HSLA) grades.
ArcelorMittal’s HI FORM (HF) products offers full spectrum of steels ranging in yield strength grades from 250 MPa to
550 MPa and tensile strength grades from 340 MPa to 590 MPa.
Advanced High Strength Steels (AHSS) is a group of steels that are more formable than the conventional HSS at
similar strength levels. The complex microstructures, containing combinations of various steel phases, are designed
into the AHSS to develop the higher strengths and better formability than the conventional HSS. These grades
include: dual-phase, stretch flanging (SF), transformation induced plasticity (TRIP) and ultra high strength steels
containing 100% martensite.
ArcelorMittal’s DI-FORM™ family of dual phase steels, having low yield-to-tensile-strength ratios are available with
tensile strengths ranging from 500 MPa to 980 MPa. Several of these grades are designed for stretch flanging (SF
grades) and high bendability (DI-FORM HB™) applications. Several of ArcelorMittal’s HI FORM steels are high yieldto-tensile-strength ratio dual phase grades and have been extensively used for auto body structural and seat parts.
ArcelorMittal’s IN-TRIP™ family of TRIP steels, with tensile strengths of 590 and 780 MPa are currently under
development. Please inquire about the status and availability of these products.
ArcelorMittal offers the automotive industry a unique set of ultra high strength 100% martensitic steels. ArcelorMittal’s
MARTINSITE® martensitic steels are available in tensile strengths from 900 MPa to 1500 MPa. ArcelorMittal’s
ELECTROSITE® martensitic steels are available with an electrogalvanizing coating for corrosion protection.
ArcelorMittal offers the automotive industry a full spectrum of steel products targeted to meet the variety of critical
design requirements necessary for the automotive part. From sheet steels that meet critical automotive exposed
quality surface requirements, to products that provide high formability, superior durability, and optimum crash energy
management, to products that offer significant corrosion protection - the ArcelorMittal portfolio of sheet steel products
can provide a cost effective solution to the requirements of the automotive engineer.
This website offers information on ArcelorMittal sheet steels for the automotive industry. Information on product
availability, steel characteristics, material properties (which include: tensile properties, formability, fatigue properties,
weldability etc.) and typical applications are among some of the details available at this website.
