 What is your wear plate IQ?
Does greater Hardness mean longer wear life?
Greater hardness does not always mean greater abrasion
resistance or longer wear life.
Several alloys may have the same hardness rating but vary
greatly in their ability to withstand abrasive wear. For
example, Arcoplate surfacing alloy derives its high abrasion
resistance from very hard carbides dispersed throughout a
softer, tougher matrix. Bulk hardness tests (Rockwell or
Brinell) measure the average hardness of both the carbide and
matrix together. As these tests are conducted over a relatively
large area, results often show the same hardness rating as
other conventional metals. However, in actual performance, a
carbide-containing surfacing alloy has a substantially better
abrasive wear resistance.
When equally comparing several surfacing alloys with each
other, high bulk hardness ratings are not the only factor
assuring resistance to wear. Resistance to low and high-stress
abrasion depends on a combination of both hardness and the
metallurgical microstructure of the alloy.
The microstructures of alloys vary according to the ratio of
carbides to matrix and the type of carbides in the alloy. The
alloy with the hardest and most evenly dispersed carbides,
along with the highest percentage of carbides, will have the
best resistance to low-stress and high-stress abrasion. Find out
