Contact us15-5 PH stainless steel combines the high strength of martensitic grades (via heat treatment) with the corrosion resistance of austenitic grades. This guide covers attributes, applications, design notes, finishing, UK stock sizes, and property tables.
15-5 PH is a modification of 17-4 PH, a precipitation hardening stainless steel with the optimal combination of the properties of martensitic and austenitic grades. It has the high strength from martensitic grades (gained through heat treatment) and the corrosion resistance of austenitic grades.
Heat treated conditions:
15-5 PH has reasonable machinability. It can be machined in the solution-annealed state or in final heat treated condition.
