WIRE ELECTRODE FOR WELDING AND SURFACING Russian patent published in 1997 - IPC

FIELD: mechanical engineering; materials for use as coated electrodes and wire electrodes for gas-shielded are welding, automatic submerged arc welding and electroslag welding of martensite, martensite-ferritice and martensite-austenitice class steels and different welded joints of these steels with perlitice class steels and surfacing of parts of with wear resistant, cavitation or corrosion resistant materials. SUBSTANCE: wire contains the following components, mas.-%: carbon, 0.03-0.2; manganese, 3.0-6.3; silicon, 0.3-0.6; chromium, 13.5-15.5; and ferrum, the balance. Content of manganese is calculated by formula: $$$ where $$$ is content of manganese, mass % and C is content of carbon, mass %. EFFECT: improved quality of welding and surfacing. 1 tbl
