WELDING MATERIAL FOR SUBMERGED ARC WELDING AND GAS METAL ARC WELDING, HAVING REMARKABLE IMPACT RESISTANCE AND ABRASION RESISTANCE

摘要

Provided is a welding material for submerged arc welding and gas metal arc welding, having remarkable impact resistance and abrasion resistance. The welding material for submerged arc welding and gas metal arc welding, having remarkable impact resistance and abrasion resistance, comprises: 0.12-0.75 wt % of C; 0.2-1.2 wt % of Si; 15-27 wt % of Mn; 2-7 wt % of Cr; 0.025 wt % or less of S; 0.020 wt % or less of P; and the balance of Fe and other inevitable impurities. Provided are a welding joint having remarkable weldability, low temperature impact toughness and abrasion resistance, and a welding material for submerged arc welding and gas metal arc welding very preferably applied to the manufacture of pipes used in the oil sand industry field and the like.
