STAINLESS STEELS
630 (1.4542) 17-4 PH Stainless Steel
630 (1.4542) 17-4 PH Stainless Steel
630 ( 1.4542) stainless steels are precipitation hardening steels with high chromium and nickel contents, providing an optimum combination of the properties of martensitic and austenitic grades. Like martensitic grades, they are known for their ability to gain high strength through heat treatment and also have high corrosion resistance.
Usage Areas :
- Defence Industry
- Petro-Chemical Industry
- Gears
- Valves and other engine components
- High strength shafts
- Turbine blades
- Moulding dies
- Nuclear waste casks
