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

摘要

The present invention relates to a welding material for submerged arc welding and gas metal arc welding, having remarkable impact resistance and abrasion resistance. One embodiment of the present invention provides a welding material for submerged arc welding and gas metal arc welding, having remarkable impact resistance and abrasion resistance, comprising: 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. According to the present invention, provided is a welding joint having remarkable weldability, low temperature impact toughness and abrasion resistance, and thus provided is 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.
