Product Description

17-4PH Stainless Steel Round Bar Overview

17-4PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, hardness, and excellent corrosion resistance. This versatile material offers good fabricating characteristics and can be age hardened by a single-step, low-temperature treatment.
