W6Mo5Cr4V2 High Speed Steel Bar
W6Mo5Cr4V2 high-speed steel is the representative steel grade of tungsten-molybdenum series general high-speed steel. The steel has the advantages of fine and uniform carbides, high toughness, and good thermoplasticity. At present, many countries are replacing W18Cr4V with W6Mo5Cr4V2 steel to become the main grade of high-speed steel. W6Mo5Cr4V2 high-speed steel has excellent toughness, wear resistance, and thermoplasticity. W18Cr4V has the same hardness, red hardness, and high-temperature hardness as W18Cr4V.
Therefore, W6Mo5Cr4V2 high-speed steel can be used to manufacture various types of general tools, as well as large-scale and thermoformed tools. . Because W6Mo5Cr4V2 steel has high strength and good wear resistance, it can also produce parts that are resistant to wear under high loads, such as cold extrusion dies, but at this time, the quenching temperature must be appropriately lowered to meet the requirements of strength and toughness. W6Mo5Cr4V2 high-speed steel is easy to oxidize and decarburize, so care should be taken during hot working and heat treatment.

Physical characteristics:
W6Mo5Cr4V2 steel is the representative steel grade of tungsten-molybdenum series general high-speed steel. The steel has the advantages of fine and uniform carbides, high toughness, and good thermoplasticity. Due to the relationship between resources and prices, many countries have replaced W18Cr4V with W6Mo5Cr4V2 steel to become the main steel grade for high-speed steel.
Application:
W6Mo5Cr4V2 high-speed steel has excellent toughness, wear resistance, and thermoplasticity. W18Cr4V has the same hardness, red hardness, and high-temperature hardness as W18Cr4V. Therefore, W6Mo5Cr4V2 high-speed steel can be used to manufacture various types of general tools as well as large-scale and thermoformed tools. Because W6Mo5Cr4V2 steel has high strength and good wear resistance, it can also make wear-resistant parts under high load, such as cold extrusion dies, etc. However, at this time, the quenching temperature must be appropriately lowered to meet the requirements of strength and toughness. W6Mo5Cr4V2 high-speed steel is easy to oxidize and decarburize, so care should be taken during hot working and heat treatment.
W6Mo5Cr4V2 steel is abbreviated as W6 or 6542, which is the representative steel grade of tungsten-molybdenum series general high-speed steel. It is a high-alloy steel containing a variety of alloying elements, which belongs to the type of ledeburite steel. It has high hardness, high wear resistance, high thermal hardness, high hardenability and sufficient plasticity and toughness, and has good casting, forging, welding and machining properties, so it occupies an important position in tool steel
The density of W6Mo5Cr4V2 steel is 8.16t/m3; the elastic modulus E is 218000MPa.
