Stainless Steel 17-7PH

Short Introduction:

HY 17-7PH/S17700/SUS631/1.4568 17/7 is a precipitation hardenable stainless. It develops its strength and hardness through heat treating. This makes it well suited for applications that require good formability, high strength/hardness and minimum distortion upon heat treating. 17/7 also provides benefits for other applications requiring high strength and good corrosion resistance, as well as excellent properties for flat springs at temperatures up to 315°C (600°F).
