Introduction:

The characteristics alloy tool steel: Cr12MoV standard: GB / T 1299-1985

Scope cold work die steel, steel hardenability sex, quenching and tempering hardness, wear resistance, high strength than Cr12. Complex shape used in the manufacture of cross-section, under heavy working conditions Die with tools, such as punching die, trimming die, trim die, steel deep drawing die, circular saw, standard tools and gauge thread rolling die.

Mechanical Properties:

Hardness: annealing, 255 ~ 207HB, indentation diameter 3.8 ~ 4.2mm; quenching, ≥ 58HRC

Cr12MoV purposes

Of the Cr12MoV die steel hardenability, hardness after quenching and tempering, high strength, toughness than CR12 diameter 300 ~ 400mm can be completely hardenability, small quenching distortion but poor high-temperature plastic. Cr12MoV used for manufacturing-section larger complex shape a heavier workload Hopewell kinds of molds and tools.

Heat Treatment Specifications

Heat treatment specifications: quenching, 950 ~ 1000 ℃ oil cooling; quenching 1020 ° C, 200 ° C tempering 2h. Microstructure: fine granular pearlite carbide. Delivery status: Delivery of steel in annealed condition.

Applications include:

Typical applications for Cr12MoV tool steel are blanking, forming, and trim dies, gages, slitting cutters, wear parts, lamination dies, thread rolling dies, drawing dies, rotary cutting dies, knurls, bending dies, gages, shear blades, burnishing tools, rolls, machine parts, master parts, injection screw and tip components, seaming rolls, extrusion dies, tire shredders, scrap choppers, etc.
