630, 1.4542, S17400, X5CRNICUNB16-4
17-4 PH Washers are martensitic stainless steel washers manufactured from alloy containing chromium and nickel with addition of copper to achieve precipitation hardening. Stainless Steel 17-4 PH Washers are used in the oil and gas, nuclear and aerospace industries where a combination of high strength, corrosion resistance and a generally low but acceptable degree of toughness is required. TorqBolt is an eminent 17-4 PH washer supplier in India.
