What is Hardness of High-carbon Steel

Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. High-carbon steel has approximately 0.60 to 1.00% carbon content.Hardness is higher than the other grades but ductility decreases. They are almost always used in a hardened and tempered condition and, as such, are especially wear resistant and capable of holding a sharp cutting edge.

Manganese steel wear liners — SRP

Austenitic manganese steel – steel alloyed with more than 10% manganese – is work-hardening. That means that high impacts – like those in a crushing chamber for example – cause the formation of a extremely hard surface layer that is two to three times harder than the rest of the alloy If impacted enough, this results in a hard exterior layer backed by a softer core.
