subject: A Specialized Heat Treatment Process For Getting A Tough Surface With A Soft Malleable Core [print this page] Even the automotive industry has ample use of the case hardening process to render tough and heavy duty metal, mostly for suspension purposes. Again, camshafts and special-purpose self-drilling screws are required to be case hardened. The process is relatively simpler for smaller items like screws and fasteners, because they can be hardened by repetitively heating and quenching. In the process of hardening for steel the metal is first carburised before being heat-treated.
