ATI 17-7™ Precipitation Hardening Alloy (S17700) is a chromium-nickel-aluminum precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. The S17700 alloy has been available for many years and has found application in aerospace and many spring type applications requiring high strength. ATI 17-7 precipitation hardening alloy may be formed in a soft austenitic condition and hardened to a high strength level by low temperature heat treatments. The low temperature allows minimum distortion compared to conventional quench and temper hardening processes. In addition to material produced by the standard refining procedures, material which has been vacuum arc or lectroslag remelted is available for further increase in resistance to fatigue, for those applications subject to cyclic stresses.
