Properties And Applications

GTA (TIG) welding rod for welding of 17Cr/4 Ni containing, 630 (1.4542) and similar precipitation hardening-martensitic stainless steels. Especially used in hydraulic equipment components, impellers, pump shafts, valves which are exposed to high corrosion in petrochemical industry, chemical plants. In order to gain precipitation hardening martensitic steel properties of the the weld metal after welding, solution heat treatment shall be done at 1052°C (±28°C) to have austenite matrix, then quenching to 149-93°C to transform the matrix to martensite and then precipitation/aging heat treatment at 482-621°C for 4 hours. After precipitation hardening heat treatment, weld metal has very high mechanical strength and high toughness, as well as very good corrosion and oxidation resistance. MIG/MAG Welding Wire: MI 630
