Abstract

The development of three new martensitic stainless steels is described. As annealed these alloys possess a relatively soft martensitic structure which is amenable to cold processing and forming operations. Two of these alloys may be strengthened from 150,000 to 200,000 psi ultimate tensile strength by means of low temperature precipitation-hardening treatments. Some physical, mechanical, and corrosion properties of these alloys are shown. The anticipated areas of application for the alloys are described.
