Is widely used cold work die steel, high strength, good hardenability and good abrasion resistance, but the poor impact toughness. Mainly used to withstand the impact load is smaller, and require high abrasion resistance Die and punch, cold-cut scissors, drill sets, gauges, drawing die, pressure die thread rolling board, drawing die thread rolling die. 

 Cr12 a high carbon and high chromium ledeburite is also widely used cold work die steel, the steel has good hardenability, wear resistance, and thermal processing. Carbides in the steel distribution better, can be used in the manufacture complex shape, a variety of cold-working die under heavy working conditions, such as Die punch, thread rolling die, drawing die, molds, metallurgy powder mold, woodworking cutting tools, cold-cut scissors drill kits and gauge tool. we developed, through repeated exploration and testing, developed a smelting process and special ingot molds and forging process, the material organization to achieve uniform material processing, in addition to the standard, bold and innovative, using two knives, a new chip technology, which greatly improved the efficacy, shorten cycle times, reducing costs.
