POWDERRANGE® 17-4 AR

UNS #S17401

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