PH-STAINLESS STEEL

Radiant Industries specializes in the production and supply of 17-4 PH Stainless Steel, also known as AISI 630 or DIN 1.4542. This is a precipitation-hardening martensitic stainless steel grade that combines high strength, excellent hardness (up to 300°C), and reliable corrosion resistance — making it ideal for critical industrial applications.

Engineered with Copper and Niobium/Columbium additions, 17-4 PH offers mechanical properties that can be precisely tailored through a variety of heat treatments.
