Tags: steel for hot work molds, alloy steel
Description Characteristics and uses: It has high tempering resistance and thermal stability, high thermal strength, high temperature hardness and wear resistance, but its toughness and thermal fatigue resistance are lower than 4Cr5MOSIV1 steel. It is suitable for making hot work molds with high requirements for high temperature strength and anti-wear performance, which can replace 3CR2W8V
This standard is applicable to hot rolled, forged, cold-drawn, silver bright bar steel and machined delivery steel of tool and die steel, and its chemical composition is also applicable to ingots, billets and their products
