MATERIAL FOR SUBMERGED ARC WELDING AND GAS METAL ARC WELDING HAVING EXCELLENT IMPACT RESISTANCE AND ABRASION RESISTANCE PROPERTIES

摘要

the present invention is excellent in impact resistance and wear resistance and a gas metal arc welding, submerged It relates to a welding material for the welding arc. One embodiment of the present invention as a weight%, C: 0.12 ~ 0.75%, Si: 0.2 ~ 1.2%, Mn: 15 ~ 27%, Cr: 2 ~ 7%, S: less than 0.025%, P: 0.020% or less , balance Fe and other impact-resistant and wear-resistant, including unavoidable impurities provides excellent submerged arc welding metal arc welding and gas welding materials. According to the invention, weldability and low-temperature impact toughness and very preferably applied to that submerged arc welding and gas metal arc welding in pipe manufacture is used, etc. Oil Sands industries anti-wear characteristics are excellent welding it is possible to provide a part For it is possible to provide a welding material.
