15-5 Stainless Steel Forgings

With its corrosion-resistance and ease of machinability, 15-5 stainless steel is ideal for applications subjected to high-pressure, such as aerospace components, valves, or shafts. Great Lakes Forge is an industry-leading provider of alloy 15-5 stainless steel forgings. We provide custom 15-5 PH steel forgings with the industry's fastest lead times. We can create custom forgings up to 4,000 lbs., from 2.5" to 24" in diameter/thickness, and up to 12' in length. Forging is ideal for long or short run production, as well as prototyping.

As an ISO 9001:2015 certified custom forging company, we offer you the flexibility and attention to detail you need in a forging manufacturer. Contact us to discuss your 15-5 stainless steel forging project or learn more about our manufacturing capabilities.

Stainless Steel 15-5 PH Properties

15-5 PH stainless steel is a martensitic precipitation hardening steel that offers high strength and high hardness. It offers corrosion resistance greater than that of straight chromium grades such as 410, and comparable to chromium nickel grades.

15-5 PH stainless steel offers excellent transverse notch toughness and ductility, and a very good uniformity of properties. It displays exceptional resistance to oxidation at high temperatures (up to 1,100°F/593°C). This material is chemically balanced to create an essentially ferrite-free microstructure, giving it a high degree of workability for forging.
