Characteristics of Cr12MoV Cold Work Mold Steel
High Hardness and Wear Resistance: With an annealed hardness of 255–207HB and a post-quenching hardness of ≥58HRC, Cr12MoV exhibits wear resistance 3–4 times higher than that of conventional low-alloy tool steels, making it ideal for molds subjected to heavy loads and high wear demands.
Excellent Strength and Toughness: Compared to Cr12 steel, Cr12MoV demonstrates significantly improved toughness, minimal volume change during quenching, and reduced quenching deformation. It can withstand impact loads, lowering the risk of fracture.
Superior Thermal Stability: Cr12MoV retains favorable hardness and wear resistance at temperatures ranging from 300–400°C, with a softening temperature of 520°C, making it suitable for high-temperature working environments.
Minimal Distortion Characteristics: It offers excellent dimensional stability after quenching, enabling the production of high-precision molds and reducing the need for subsequent machining.
Good Machinability:
Processability: Easy to cut, drill, mill, and grind, facilitating the manufacture of molds with complex shapes.
Weldability: When subjected to appropriate welding processes, it achieves strong weld joints, simplifying mold repair and modification.
Outstanding Compressive Strength: Cr12MoV features high compressive strength, making it suitable for manufacturing molds and tools that endure heavy loads.
