AMS 5622 /17-4PH Stainless Steel Bar is a nickel-chromium precipitation-hardening stainless steel suitable for applications requiring much higher strength, toughness and good corrosion resistance.
UNS S17400 / PH17-4 Stainless Steel Bar offers various attractive performance characteristics. Possesses good stress corrosion resistance, high fatigue resistance and resistance to galling. 17-4PH is readily weldable by all conventional methods, and there is no requirement for pre or post-heating, which is usually the case for standard hardenable stainless steels. A single, low-temperature heat treatment will harden the alloy.
