For the sake of this article, the selection of the steel grade will not be discussed. The writer assumes that metallurgical and mechanical engineers were consulted for the selection of the steel to be used in a given application. Heat-treatable materials, however, are a requisite part of the application. Heat treating steel for optimum strength and ductility consists of a hardening process followed by tempering.
