17-7 Ph Stainless Steel Springs
UNS S17700, AISI 631, 632; ASTM A313; AMS 5529, 5678
17 7 Ph Stainless Steel Springs are cold drawn springs with a better corrosion resistance as compared to 302/304 springs and 316 springs. 17-7ph Stainless Springs are used for high temperature applications without magnetism. 17-7 Ph Springs are precipitation hardened stainless steel alloy springs . These springs are semi-austenitic being austenitic in the annealed condition and martensitic in the hardened condition. Alloy 17-7 PH Springs provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion upon heat treatment. We at TorqBolt manufacture wire springs & Flat Springs forms.
