Austenitic rubber alloy welding rods, with their high carbon content, are designed for welding high-temperature components made from corrosion-resistant chromium-nickel steels of grades 08Kh18N10, 12Kh18N9, AISI 304, 304H, 1.4948, and similar grades, where the weld metal does not require strict intergranular corrosion resistance, and even when not in contact with sulfur-containing environments. Simultaneously, the welded metal exhibits high overall corrosion resistance.
Due to the higher carbon content, the welded metal resists plastic deformation at operating temperatures up to 550°C, and due to the low ferrite content, it resists brittleness at temperatures up to 700°C and cracking at high temperatures up to 800°C. It is used in the chemical and petrochemical industries for welding flame tubes, cyclones, and boilers.
