1. W18 / W18Cr4V / T1 Introduction: W18Cr4V is tungsten high speed tool steel with high hardness, red hardness and high temperature strength, at 500 ℃ and 600 ℃, the hardness still are maintained at HRC57-58, HRC52-53, In addition, it also has good high temperature strength and wear resistance, the treatment temperature range is wide, easy to overheat hardening, easy to grinding, thermal processing and heat treatment process is not easy to oxidation and decarbonization. General to be processed material has good machinability. Carbide of the steel, high-temperature plasticity than molybdenum high-speed tool steel is poor. W18Cr4V cast organizations, including the form of bone-shaped, carbide flake with martensite or troostite alternating with ledeburite, as well as the Black Bloc (δ segregation) and white organization (martensite and residual austenite) . Cast microstructure and chemical composition of high-speed steel is particularly uneven, and heat treatment does not change, and therefore must be pressure processing, the coarse eutectic carbides smashed and homogenized, and then use to manufacture all kinds of cutting tools and mold. 2. Features: high wear resistance, high compressive strength, high surface hardness after hardening, good overall hardenability, good surface treatment, excellent resistance to temper softening W18Cr4V 3. Uses high-speed steel applicable in cutting tools, such as twist drills, broaches, tapping, milling cutter, cutter, cutter knives and other cutting tools. W18Cr4V also applies to indirect cooling applications; for example: punching, forming, stamping and the like. Balance: High-alloy cold wear resistance and toughness excellent combination of steel jobs. The heat treatment process annealing temperature is 870-880 degrees, heat for 2-3 hours, then preheated 800-840 degree, the degree of quenching from 1270-1280, grading temperature is 580-620, then 560 degrees three times tempering, incubated for 1 hour tempering 5. Delivery size φ2-16mm - cold drawn materials φ10-55mm - hot-rolled material φ50-190mm-- conventional forging material 6. Delivery condition: Cold drawn / Hot-rolled / fine forging / annealing skin color: black color / silver light (car light peeling / grinding stripping / Precision straightening hanging oil) The company specializes in the production of various grades of high-speed steel: 6542,9341, W18, M2, M35, M42. According to customer development of practical applications of new steel grades. Paul chemical composition, security testing can single contact with the original material production. 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, complete specifications, hot-rolled + cold drawn material + forgings are online production, the chemical composition of insurance, security testing can take the raw material of single contact
