17-4 PH (EN 1.4542) Stainless Steel Strip & Coil – High-Strength Precision Alloy
Lork Group is a trusted manufacturer and supplier of premium 17-4 PH (EN 1.4542) stainless steel strips and coils in China. This precipitation-hardening martensitic stainless steel delivers an exceptional balance of strength, corrosion resistance, and machinability, making it a superior alternative to conventional grade 304 stainless steel for demanding applications.
High Strength
Achieves tensile strengths up to 1,300 MPa through heat treatment (H900, H1150, etc.).
Excellent Corrosion Resistance
17-4 PH's high chromium and nickel content resists oxidation, acids, and cyclic corrosion.
Precision Weldability & Machinability
Retains ductility and toughness post-fabrication, ideal for complex components.
Customizable Hardness
Properties can be tailored via thermal aging to meet specific mechanical requirements.
