SKD61 die steel Purpose:
SKD61 die steel is a medium alloy hot work die steel containing silicon, chromium, molybdenum and vanadium. After quenching and tempering, it can obtain fine and moderate grain martensite, which is basically distributed with fine carbonization. It has good comprehensive mechanical properties and good hardenability. It is more suitable for manufacturing large size and complex shape dies.
characteristic 1. High temperature strength and toughness, good wear resistance, easy to cut; SKD612 and SKD61 are hot die steels with good strength, toughness and heat resistance balance. In recent years, with the development of isotropic products, they are increasingly developing to high toughness and other aspects. They can make dies have longer service life, more stable performance, and are easy to process, heat treatment Small deformation. purpose
SKD61 is widely used as die material for aluminum and zinc die-casting. This steel contains tungsten high temperature resistant alloy steel, which is suitable for hot work, aluminum, magnesium, zinc and copper alloy die-casting dies, grooving knives, scissors and hot forging actions, plastic molds, hot work reamers, rolling knives, general hot work forging dies, hot bolt dies, hot room tools, etc.
SKD61 hardness:
SKD61 is about HRC15~20 (HB200~230) before heat treatment Hardness after heat treatment: internal HRC40 °~45 ° surface HV1000 ± 100 The density of SKD61 is 7.85g per cubic centimeter SKD61 die steel Typical application examples 1) It is used to make aluminum alloy die-casting dies. When the hardness is 40-46HRC, the service life is relatively long, reaching 45000-65000 times. 2) It is used to make hot forging punches for bearing ring blanks (Φ 31 - Φ 33mm), 80-100 times/min high-speed pier forging * * *, and spray water to cool the punches during use. When the hardness is 50HRC, the service life is 2 430000 times, better than 3Cr2W8V steel.
