FLUX-CORED ARC WELDING MATERIAL HAVING EXCELLENT IMPACT RESISTANCE AND ABRASION RESISTANCE PROPERTIES

摘要

The present invention relates to a flux-cored arc welding material having excellent impact resistance and abrasion resistance properties. An embodiment of the present invention provides the flux-cored arc welding material having the excellent impact resistance and abrasion resistance properties comprising: C: 0.1 to 0.75%; Si: 0.2 to 1.2%; Mn: 15 to 27%; Cr: 2 to 7%; S: 0.01% or less; P: 0.018% or less; TiO_2: 4.3~15%; at least one type selected from a group consisting of SiO_2, ZrO_2 and Al_2O_3: 0.01 to 9%; the remnant Fe; and other inevitable impurities on the basis of weight%. In accordance with the present invention, a welded joint with excellent weldabillty, low-temperature impact toughness and abrasion resistance properties, which is capable of all position welding, can be provided, thereby supplying welding materials capable of being applied to pipe manufacturing for use in the oil sand industry field and the like.
