15-5 stainless steel

- Feb 15, 2021-

1、Stainless Steel 15-5 is a precipitation hardening martensitic stainless steel designed to have a greater toughness than 17-4 ph stainless steel. It is used in applications requiring better corrosion resistance and transverse properties compared to other similar martensitic grades. Strength and toughness desired can be altered by temperate range in the heat treatment process.

2、15-5 stainless steel is a martensitic, precipitation-hardening material with chromium, nickel and copper. It is often a first choice in the aerospace industry for fasteners and structural components. Its unique structure provides increased toughness and better corrosion resistance than its predecessor, 17-4 PH. Both inclusion control and a minimized amount of delta ferrite as compared to 17-4 stainless steel contribute to the greater toughness of 15-5.

Common Applications of 15-5 PH

1. Aerospace applications


3.Oil & Gas applications

4.Power generation

5.Valves, gears and pumps

6.Food processing
