DF-7040 as been developed specially for the forging industries. It is utilized for partial repair and for finishing dies and component surfaces,to eliminate low spots, and undercuts where flood welding has been performed. Lime coated electrode for facings in high speed tool quality for reinforcement of cutting edges of tool bodies made of unalloyed steel and for the lining of hot cutting tools. The weld deposit can be heat treated like high speed tool steel of similar composition and has retention to hardness up to 550°C. An Increase in hardness up to 63-65 HRC is achieved by tempering.
Hot working punches and dies extrusion mounds and dies, shear blades milling and cutting tools, cutting edges of stamping dies and swaging hammers wood cutting tools.
