Detailed Product Description: | The 1.W18Cr4V is a high speed steel, hardness 62 ~ 65HRC for cutting tools, such as cannabis, anchor, broaches, tapping, milling, washing, cutting off the reamer and other. To performance in terms of W18Cr4V is a full range of steel, rigid thermal requirements are not the most important case can be used to cut. 2 w18cr4v chemical composition: C: ≤ 0.70 Si: ≤ 0.40 Mn: ≤ 0.40 Cr :3.80-4 .40 V :1.0-1 .40 Mo: 0.30 P: 0.03 S: 0.01 W :17-19 3 features: High wear resistance High compressive strength High surface hardness after hardening Excellent overall hardenability Surface treatment processing (4) heat treatment process: Excellent resistance to tempering heat treatment process treatment is annealing temperature of 870 to 880 degrees, heat 2 to 3 hours, then 800 a 840 degree preheat quenching from 1270 a 1280 classification, the classification temperature of 580 620, then 560 degrees three times tempering, tempering for 1 hour. W18Cr4V contain large amounts of alloying elements: poor plasticity, thermal conductivity, rapid heating when the thermal stress crack deformation, so be heated to quenching temperature 1270 to 1280 degrees in a 800 to 840 warm-up, complex shape, but also increase the time warm-up in 500 a 650 V, W, starting to improve red hardness elements to a high temperature until dissolved, but the high temperature will make the coarse grains, and W and other alloying elements reduce the Zone A , making the eutectoid and eutectic temperature has increased, and thus select one 1270 1280 degrees of direct air cooling, precipitation of secondary carbides, thereby reducing the red hardness of steel. The hardened organizations for M 10 carbide ten residual A (up to 30%) of 550 and a 570 degree tempered precipitation of WC caused by secondary hardening, A decomposition, analysis of C, to reduce the content of alloying elements, make Ms rising, resulting in secondary quenching and a tempering, residual A3, 15% of the residual A second tempering% to 5% Three tempering, only 1% to 2%, and ultimately have the temper of M 10 carbide ten very small amount of residual |
