High-austenite alloy welding rods are designed for welding products made from heat-resistant, anti-settling steels of 25% Cr-20% Ni, such as 20Kh23N18, AISI 310S, X15CrNiSi25-21, 1.4841, and similar steels, operating at high temperatures and mechanical loads in oxidizing and chemically aerated environments (not suitable for use in fluorescent environments). The completely austenitic structure of the weld joint ensures no brittleness during long-term operation at temperatures from 550 to 950°C. However, for the same reason, the possibility of hot cracking of the welded metal must be taken into account during welding.
Due to its high chromium content, the weldable metal can achieve anti-settling properties at temperatures up to 1150°C. The specific heat input cannot exceed 1.5 kJ/mm² and the temperature between weld layers cannot exceed 100°C. The welding electrode must be ferrite-free.
