ABSTRACT:
A steel hardening by precipitation in a martensitic matrix and having an iron-nickel, iron-chromium, or iron-manganese basis is austenitized and then subjected to a heat treatment including heating it to at least 500.degree.C. This hardens the steel and at the same time increases its coercive force.
