A continous solid corrosion resisting chromium-nickel-molybdenum-copper wire for welding of austenitic stainless alloys of 20% Cr, 25% Ni, 5% Mo, 1,5% Cu, low C types. OK Autrod 385 weld metal has a good resistance to stress corrosion and intergranular corrosion and shows a very good resistance to attack in non-oxidizing acids. The resistance and crevice corrosion is better than for ordinary 18% Cr, 8% Ni, Mo steels. The alloy is widely used in many applications related to the process industry.
