3Cr2W8V hot work die steel to improve wear resistance 0057.256.5650S1.550.9 Yuan Temple High Shear 66.755060.358.5 Figure 22 × 1.5h tempering and 000 fire,franklin and marshall, there are high red hardness, hardness decreased less. that about 600 ℃ and the precipitation of carbides, w, 0, V were higher, so there is good stability,ed hardy sverige, not too grown up for carbide softening. 3.3.3 wear one in the MM 200 on the abrasion wear test machine test, test, wear scar width of samples obtained by carburizing treatment is better than no carburization resistance. which carbon carburization casting and forging potential heat - heat quenching practice 1998.No.2-251080 ℃, 600 ℃ tempered by the best, because the carbon potential is too low, the formation of the carbide is insufficient,ed hardy suomessa, wear little contribution carbon potential is too high, the local formation of network carbide, spalling occurred in the wear and tear, resulting in increased wear. 4. production test pilot for a mold with 0.9 1.IC carburizing carbon potential, and then by 1080 ℃ quenching,christian louboutin sko, 600 ℃ × 1.5 小时 second tempering. Anti-extrusion head, anti-extrusion die, cut the end of the punch, expansion of the movement to improve life touched more than twice. test the stability of the mold in size, to facilitate mold release and mold and other aspects of life are much higher than the conventional quenching heat treatment of the mold. This not only saves cost of steel and die,Christian Louboutin, while saving processing and assembly and disassembly of mold work and energy, increase production efficiency. 5. Conclusion small tonnage of stamping machine work 3Cr2W8V steel,ed hardy bikini, the carbon potential of 0.9 ~ 1.1C, 930 ℃ ± 1O'C carburizing treatment,franklin marshall milano, 1080 ℃ heating oil quenched 6. 0 ℃ tempered with good wear resistance and red hard.

Machine Industry Press Du igSl Nanjing city photo furnace (Group) Co., Ltd ~ ~ Electric Furnace Plant of Nanjing photo mountain atmosphere of microprocessor-based protection with no muffle furnace unit chain This series of units from the previous washing machine, the feeding mechanism,ed hardy kläder, chain belt type heating Shanghai, quenching tank, after the washing machine, furnace, electric drive control cabinet, the temperature control cabinet and high-purity chlorine machine. the production process can be fully automated t using a variety of computer control, manufacturing high sensitivity, a large load of more than 2 times the mesh belt furnace for the continuously variable transmission system - easy to adjust the process; chain with high temperature heat-resistant steel sheet metal forming long life, easy maintenance; quenching furnace use of electric radiant tube heating,ed hardy mexico, energy conservation measures with special sealing effect is remarkable. is mainly used for mass production of bearings, the outer ring and washers, bolts, nuts and other standard parts of the light (or smooth) quenching and heat treatment, can also be used a certain load parts bright quenching, tempering,magasin abercrombie, carburizing, carbonitriding buildings. The main technical parameters (see table) This unit has won seven countries - Five Star Plan Gold t93 gold medal in the national Spark Program drawer, and in 93 Electrical and Mechanical Services Department in June through the level appraisal, is the domestic bearing industry ideal for heat treatment equipment.
