Weldtool tool steel type H-12 is a hot working tool steel alloy. It has excellent hot hardness, wear resistance and displays reasonable impact resistance. The as welded hardness is 50 – 55 HRCWeldtool tool steel type H-12 is used for repairing or building of hot and cold trim and shearing dies, punches, extrusion dies and die casting dies. It is an excellent choice for press forging dies where high heat and abrasion are encountered. A typical application is the automobile connecting rod forging. High volume forgings that demand the ultimate in weld metal mechanical properties would be connecting rod, sleeve yoke, and hand tools. These applications are relatively shallow and usually high production. Other forged products would include earth moving equipment and farm implements, hooks and lever brake bands and other shallow impressions, such as hand tools, pipe wrenches, and crankshafts.
