The salient features of its salient features with high hardness, wear resistance and hot hardness (also known as red hardness), when the the Cutlery temperature up to about 500 to 600 degrees Celsius, the hardness no noticeable decline more than low-alloy cutting tools steel can also be used in the manufacture of high-speed cutting, mainly used in the manufacture of high cutting speed, heavy load, high temperature cutting tools, such as turning, milling, hob, planer, broaches, drills, taps, etc., hot and cold deformed mold require high abrasion resistance, high temperature spring, high temperature bearings. Implementation of standards W6MO5CR4V2 pictures: Standard: GB / T 9943-1988 physicochemical characteristics physical characteristics of W6Mo5Cr4V2 of steel tungsten and molybdenum-based general-purpose high-speed steel on behalf of steel number. The steel has a fine and uniform carbide, high toughness and good thermoplastic. Because of the relationship between resources and prices, many countries have a number of high-speed steel steel. W6Mo5Cr4V2 steel replaced W18Cr4V The Scope W6Mo5Cr4V2 high-speed steel toughness, wear resistance, thermoplastic excellent W18Cr4V, and hardness, red hardness, high temperature hardness and W18Cr4V quite, so W6Mo5Cr4V2 high speed steel, used in the manufacture of various types of general tools, but also the production of large and thermoplastic forming tools. High W6Mo5Cr4V2 steel strength, abrasion resistance, wear-resistant parts under high load and therefore can be produced, such as cold extrusion die, but must be appropriate to reduce the quenching temperature in order to meet the strength and toughness requirements. W6Mo5Cr4V2 high speed steel is susceptible to oxidation and decarbonization, thermal processing and heat treatment should be noted. W6 or 6542 W6Mo5Cr4V2 steel referred to, on behalf of the steel grade of tungsten and molybdenum-based general-purpose high-speed steel. It contains a variety of high alloy steel alloying elements, to the case ledeburite steel types. With high hardness, high wear resistance, high fever, rigid, high hardenability and sufficient ductility and toughness, and good casting, forging, welding and machining performance tool steel, and thus it occupies and important position in steel No. (GB) (NF), France, the United States (AISI) Japanese (JIS), Germany (DIN) W6Mo5Cr4V2 M2 SKH51 HS6-5-2 1.3343s of W6Mo5Cr4V2 steel density 8.16t/m3; elastic modulus E 218000MPa.
