A precipitation hardenable chromium-nickel-copper grade, Alloy 17-4 offers excellent corrosion resistance, high creep rupture strength and high tensile strength.
Most commonly used in the oil and gas, aerospace and motorsport markets, Alloy 17-4 offers excellent corrosion resistance, high creep rupture strength, high tensile strength and hardness.
We stock Alloy 17-4 in a variety of product forms to suit different applications and fabrication methods, including plate, round bar and sheet. To view available sizes and submit an inquiry, use the dropdown selector below.
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.
