Fully austenitic stainless steel wire electrode for GMA (MIG/MAG ) welding of heat resistant steels, containing approx. 25% chromium and 20% nickel, which are used in heat treatment and industrial furnaces and equipments, like cement and steel industries. Also suited for welding heat resistant and scaling resistant ferritic chromium steels, provided that corrosion attack by reducing sulphur-bearing combustion gases is not be expected. Weld metal exhibits good toughness down to -196°C and non-scaling up to 1200°C
