W6Mo5Cr4V2 quenching temperature: 1210-1230 annealing temperature: 840-860 To stress annealing: 720-760 quenching medium: less salt bath 600 ℃, can also be air-cooled oil cooler or normal tempering temperature: 540-560 quenching and tempering Rockwell : 63-66 M2 M2 States to list the chemical composition of stars is molybdenum high-speed steel with high toughness carbide of the advantages of small and easy to overheat, it should be strictly controlled quenching temperature, heat treatment due to the more stringent protection requirements. Its hardness and wear resistance, used for the manufacture of cutting tools difficult to cut materials .M2 high-speed steel carbide has a larger tendency, so the heat treatment more stringent protection requirements, suitable to withstand vibration and shock loading of the mold. Factory hardness: ≤255HB. Hardening temperature: 1220-1240, hardness: ≤63, the main purposes: cold forging die, precision dies, powder pressing molds, die cutting machine, add the plastic glass and the like. Suitable to withstand vibration and shock loading of mold: deep-drawing die, punching die. Metal cutting saw blade, cold heading and extrusion tools. Cold-drawn hot-rolled sheet production forgings are we to provide professional selection of proposals, precise processing, efficient logistics and distribution and after sales service. Help customers reduce costs, starting from the source to build competitive advantage. The company: specializes in producing high-speed steel, according to customer development of practical applications of new steel grades. Hot-rolled bars, plates, slats, profile and cold drawn material, forging material. Electro-slag re-melting, carbide small, wherein the carbide particle size of the United States cold-drawn material testing, to 8.5 microns, far higher than the national standard. Tight Control of low magnification and P, S and other impurities for steel. Implementation of corporate-controlled chemical composition standards up to national standard midline about providing quality assurance *, affordable, quality assurance.
