Cr12MoV steel has high hardenability, cross section from 300 to 40 0㎜ or less completely hardenability at 300 ~ 40 0 ??℃ while still maintaining good hardness and wear resistance, toughness, higher than the Cr12 steel, quenching the smallest volume change . Section can be used to manufacture large, complex shape, subjected to a large impact load of various molds and tools. For example, the complex shape of the punching die, complex mold inserts on the steel deep drawing dies, drawing dies, thread setback silk panels, cold extrusion die, cold cut scissors, saw, standard tools, measuring tools. Characteristics Alloy tool steel: Cr12MoV Standard: GB / T 1299-1985 scope cold die steel, steel hardenability, quenching and tempering hardness, wear resistance, high strength than Cr12. For the manufacture of large cross-section, the shape of the complex, under heavy working conditions and a variety of Die tools, such as punching die, trimming die, trim molding, deep drawing steel mold, circular saws, standard tools and gauges, thread rolling die and so on.
