About Alloy 17-4
Alloy 17-4 is an age-hardening martensitic stainless combining high strength with the corrosion resistance of stainless steel.
The alloy maintains high tensile strength and hardness up to 316°C and excellent oxidation resistance up to 593°C. Alloy 17-4 has good creep-stress rupture properties up to 482°C.
Hardening is achieved by a short-time, simple low-temperature treatments. Unlike conventional martensitic stainless steels, such as type 410, Alloy 17-4 is more weldable.
The strength, corrosion resistance and simplified fabrication can make Alloy 17-4 stainless a cost-effective replacement for high strength carbon steels as well as other stainless grades.
