Cr12MoV steel has high hardenability, cross-section of 300 to 400 mm or less can complete quenching 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, withstand greater impact loads of various molds and tools. For example, the complex shape of the punch die, mold inserts on the complex, steel deep drawing die, drawing die, silk thread setback plate, cold extrusion die, cold cutting scissors, saw, standard tools, measuring tools. Alloy tool steel: Cr12MoV [1] Standard: GB / T 1299-2000 long steel Cr12MoV Scope cold die steel, steel hardenability, quenching and tempering hardness, wear resistance, high strength than Cr12. For the manufacture of large cross-section, complex shape, under various operating conditions onerous Die and tools, such as punching die, trimming die, trim molding, steel deep drawing dies, circular saw, standard tools and gauges, thread rolling die. Availability varieties Rolled, forgings, cold-drawn material, hot-rolled and cold-drawn steel wire back, hardness 255 ~ 207HBW, indentation diameter 3.8 ~ 4.2mm. Chemical Composition: Carbon C: 1.45 ~ 1.70 Si Si: ≤ 0.40 Manganese Mn: ≤ 0.40 Sulfur S: ≤ 0.030 Phosphorus P: ≤ 0.030 Chromium Cr: 11.00 ~ 12.50 Ni: to allow the residual content of ≤ 0.25 Copper Cu: to allow the residual content of ≤ 0.30 vanadium V: 0.15 ~ 0.30 Mo Mo: 0.40 ~ 0.60 Mechanical Properties: Hardness: annealing, 255 ~ 207HB, indentation diameter 3.8 ~ 4.2mm; quenching, ≥ 60HRC Cr12MoV use Cr12MoV die steel hardenability, after quenching and tempering hardness, strength, toughness, CR12 higher than the diameter of the workpiece 300 ~ 400mm or less completely hardenability, small deformation hardening, but poor high-temperature ductility. Cr12MoV used for manufacture of large cross-section, complex shape, heavier workloads kinds of molds and tools together. Such as punching die, trimming die, trim molding, steel and so on.
