Description
Stainless Steel 17-7PH
17/7PH alloy 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).
17-7PH forgings, bars, plates, strips, rings, wires, flanges, etc. produced by Shanghai HY Industry Co., Ltd can be produced according to customer requirements, and are widely used in electric power, petrochemical, shipbuilding, machinery , Electronics, environmental protection and other industries.
