PowderRange® 15-5PH

UNS #S15500

PowderRange® 15-5PH stainless steel is a martensitic precipitation/age-hardening stainless-steel similar to 17-4PH offering higher strength and hardness, along with excellent corrosion resistance, up to 600°F (316°C). It has good fabricating characteristics and can be age-hardened using a single-step, low temperature treatment that can be chosen to achieve specific strength and toughness combinations. Due to this balanced combination of performance and ease of use in AM, 15-5PH stainless steel has been used for a wide variety of additive manufacturing applications, including rapid tooling, functional components in nearly every market, and prototyping.
