APPLICATION
56NiCrMoV7 is suitable for manufacturing various large and medium-sized pressing molds, extrusion tools, support tools and mold bases. Large molds for thermoplastic plastic treatment.
56NiCrMoV7 Steel Characteristics
56NiCrMoV7 mold steel is an oil quenched and gas quenched plastic mold steel with excellent hardenability, toughness, and heat resistance. This material is also suitable for use as cold working tool steel because it can maintain high hardness and strength. In addition, 56NiCrMoV7 mold steel also has good polishing performance and is suitable for surface treatment.
In terms of chemical composition, 56NiCrMoV7 mold steel contains 0.5% carbon, 1% chromium, 2% nickel, and a small amount of elements such as molybdenum and vanadium. The presence of these elements endows 56NiCrMoV7 mold steel with high hardenability, wear resistance, thermal fatigue resistance, and low deformation rate.
During the heat treatment process, 56NiCrMoV7 mold steel can change its physical properties through forging, softening, annealing, quenching, and tempering. Specifically, its softening annealing temperature is 850-950 ℃, quenching temperature is 800-850 ℃, and tempering temperature is 500-600 ℃. After such a heat treatment process, 56NiCrMoV7 mold steel can achieve a hardness of HRC 36-52 at room temperature.
Overall, due to its excellent performance, 56NiCrMoV7 mold steel is widely used in the manufacturing of plastic molds, cold working tools, die-casting molds, etc.
