Introduction:HBW-50G is a kind of low alloy steel copper-plated welding wire. Because Mo and Ti elements are appropriately added into welding wires, the strength and toughness of weld seams are improved, the crystal grains are strengthened, and when the welding wires are used, the advantages of less splashing, smooth wire feeding and beautiful formation are achieved.
Application:It is applied to welding 600MPa-class low alloy steel in pipes, bridges, automobiles, steel structure, etc.
