630 Stainless Steel Plate 17-4PH Precipitation Hardening for Aerospace 1.5-100mm Thick

630 (17-4PH) Stainless Steel Plate

Our 630 stainless steel plate, also known as 17-4PH (UNS S17400 / SUS630), is a martensitic precipitation hardening stainless steel that delivers an outstanding combination of high strength, hardness and corrosion resistance. Supplied in Condition A (solution annealed) and aged conditions from H900 to H1150, it is ideal for demanding aerospace, chemical and petrochemical applications.

Key Features

• High strength – tensile strength up to 1310 MPa in the H900 condition.
• Precipitation hardening – simple low temperature aging achieves high strength with minimal distortion.
• Good corrosion resistance – superior to 304 and comparable to 430 in many environments.
• Excellent machinability in the solution annealed condition.
• Full traceability – EN 10204 3.1 mill test certificate and third party inspection (SGS / BV) available.

Specifications
