WebWhen we talk about case hardening, we're talking about steels whose compositions are often referred to as mild steels. That is, a plain carbon steel with about three-tenths of a percent carbon in it, and, on occasion, alloy steels, which contain elements like molybdenum and chromium. And those elements are the ones that are responsible for ... WebFlame or induction hardening are processes in which the surface of the steel is heated to high temperatures (by direct application of a flame, or by induction heating) then cooled rapidly, generally using water; this creates a “case” of martensite on the surface. A carbon content of 0.4–0.6 wt% C is needed for this type of hardening.
