Stainless Steel 15-5 Product Guide

Applications | Stainless 15-5 Specifications | Mechanical and Chemical Data | Tolerances

Overview

15-5 stainless steel is a martensic, precipitation hardening steel designed for higher strength than 17-4 stainless. The higher strength comes at the cost of lower corrosion resistance at higher temperatures. Typically used in aerospace, petrochemical applications, pulp and paper machines, and food productions.
