Detailed Product Description: | Cr4W2MoV is a new type of alloy steel cold die steel, more stable performance, the life of the mold than the Cr12, Cr12MoV steel has greatly improved. The main features of Cr4W2MoV steel eutectic carbide particles are tiny, evenly distributed, with high hardenability and hardenability, and has good wear resistance and dimensional stability. The steel thermal processing temperature range is narrow, large deformation resistance. The practical use of proven good performance Cr4W2MoV steel cold die steel, used to make all kinds of dies, cold heading die, blanking dies, cold extrusion die and mold setback silk panels. Features: This is for the shortcomings of Cr12 steel steel and developed a generation of steel, has good abrasion resistance and secondary hardening capabilities. The steel eutectic carbide particles small, evenly distributed, with high hardenability and hardenability, and good wear resistance and dimensional stability. But steel thermal processing temperature range is narrow, large deformation resistance. To obtain ≤255HBW hardness, isothermal duration of the steel can not be less than 6 ~ 8h. Hardened Depth: φ150mm × 150mm, can be inside and outside quenching, the hardness of 60HRC, air quenching depth: 40 ~ 50mm. The steel performance is relatively stable, its life than die Cr12, Cr12MoV steel has greatly improved. The steel forging temperature range narrow, easy-to overheating, burning, forging crack. Methods of Cr12 steel can be forged. φ98mm quenched specimens in 980 ℃ air-cooled quenching? after its core hardness reaches 58 ~ 60HRC, surface hardness of 63 -67HRC. Quenching at a temperature of 1020 ° C, the tempering at 400 ° C is preferably toughness; at 500 ~ 520 ° C tempering after 1 to 3 times, better secondary hardenability, toughness decreases, rendering peak flexural strength compressive yield strength steel than Cr12MoV high of about 10%. The deformation hardening steel and Cr12 steel lines similar trends, better scalability. Delivery status: available varieties of hot-rolled sheet, forgings. Hardness ≤269HBW ingredients:. C Si Mn Cr W Mo VPS 1.12 ~ 1.25 0.40 ~ 0.70 ≤0.40 3.50 ~ 4.00 1.90 ~ 2.00 0.80 ~ 1.20 0.80 ~ 1.10 ≤0.030 ≤0.030 heat treatment process: the steel annealing soften more difficult, the general use of isothermal ball annealing. Annealing process: heating temperature of 850 to 870 degrees, heat 4 ~ 6H, isothermal temperature of 760 degrees, heat 6 ~ 8H, furnace cooling to below 600 degrees baked cooled, hardness 229HBW. Quenching temperature of 960 to 980 degrees, oil cooling or air cooling, the hardness of 62HRC; tempering temperature of 280 to 300 degrees, tempering 3 times, each 1H. Tempering hardness 60 ~ 62HRC. High temperature quenching, tempering (1030 degrees quenching, tempering 520 degrees three times) mold steel with high wear resistance and hot hardness. A lower temperature quenching, tempering lower temperature (900 to 980 degrees quenching, tempering 200 to 290 degrees) of the mold has good strength and toughness. Typical application examples: 1) is mainly used for silicon steel blanking die. 2) The steel used to make the material thickness> 3mm complex shapes punching die punch, die, inserts, it is recommended when making punch hardness 58 ~ 62HRC, recommended the production of die hardness 60 ~ 64HRC. 3) for the production of stamping molds requiring high wear resistance, complex shape of the punch, die and inserts, it is recommended when making punch hardness 60 ~ 64HRC, recommended that the production of die hardness 60 ~ 64HRC. 4) for aluminum, copper, steel concave touch of cold extrusion die, die proposal hardness 62 ~ 64HRC. 5) for the production of dies, cold heading die, blanking die, drawing die, cold extrusion concave touch and rub silk panels. 6) is a large-scale production batches or Die quantities of basic steel. 7) the use of die steel refrigeration upsetting deformation normalizing + + isothermal ball annealing temperature quenching, tempering + sulfur, carbon, nitrogen triple penetration composite toughening deal with new technology, can improve the mold base on the basis of strength and toughness, improve the mold cavity surface layer hardness and wear resistance, effectively improve the life of the mold. 8) Cr4W2MoV steel punch uses 1020 ° C heat, 260 ° c × 1h Austempering, 220 ° C × 1h × 2 times tempering hardness of 58 -59HRC. The average life of the mold 898. 9) leaf spring punching punch original use Cr12MoV indium, die life is 265, and use Cr4W2MoV steel, punch life of 491, such as a steel punch Cr4W2MoV were 920 ℃ × 4h bath vanadizing use life of up to 845.
