Cr12MoV hot rolled steel round bars

Cr12MoV steel has high hardenability, and those with a cross-section of 300 to 400 mm or less can be completely quenched. It can maintain good hardness and wear resistance at 300 ~ 400℃, its toughness is higher than Cr12 steel, and its volume change is minimal during quenching. It can be used to manufacture various molds and tools with large cross-sections, complex shapes, and withstand large impact loads. For example, punching dies with complex shapes, inserts on complex dies, steel deep drawing dies, wire drawing dies, threaded wire plate, cold extrusion dies, cold cutting scissors, circular saws, standard tools, measuring tools, etc.
