Abstract
Provided is a flux-cored arc welding material having remarkable impact resistance and abrasion resistance. The flux-cored arc welding material having remarkable impact resistance and abrasion resistance comprises: 0.1-0.75 wt % of C; 0.2-1.2 wt % of Si; 15-27 wt % of Mn; 2-7 wt % of Cr; 0.01 wt % or less of S; 0.018 wt % or less of P; 4.3-15 wt % of TiO2; 0.01-9 wt % of at least one selected from the group consisting of SiO2, ZrO2 and Al2O3; and the balance of Fe and other inevitable impurities. Further provided are a welding joint capable of all-position welding and having remarkable weldability, low temperature impact toughness and abrasion resistance, and thus a welding material very preferably applied to the manufacture of pipes used in the oil sand industry field and the like.
