9 cr2mo materials for typical Cr2 cold roll steel is mainly in the industrial used in the manufacture of cold rolled with the roller of roller of cold die and punch etc forging but many say don't know about 9 cr2mo heat treatment method, so here mainly to talk about 9 cr2mo heat treatment method, hope to be of spheroidizing annealing: 1 790 ~ 810 heating, isothermal, 650 ~ 670, 500 from air cooling;2淬火:加热温度= 880〜900,淬火冷却:根据不同的疑问和不同的要求,可以使用冷却介质,例如水上PAG淬火液体油。
注意:字子2是典型的CR2冷卷钢。
3临界点温度(近似值):AC1 = 740 C AR1 = 700 C ACCM:850 C 4冷式空白的常见软化规格820 10)c 3〜4h,冷却速率为15 c /h,炉子缓慢冷却至650 c,从烤箱冷却到纺锤体柔软的柔软规格中的5冷空白
820 10) C 3 ~4h, (720 10) C 6 ~8h, then with the furnace slowly cooling to 600 C,Specification for normalizing: normalizing temperature 900 ~920 C, hardness 302-388HBW 7 Batch isothermal spheroidizing Annealing :790 ~810 C 2 ~3h, furnace cooling, 7O0-720 C 3 ~4h, hardness 217HBW, Pearlitic tissue 2-5级,淬火和调速的规格8块网状碳化物2 1。淬火温度830-850 C,硬度62-65 HRC,回火温度130-150 C,硬度62-65 hrc 2。淬火温度840-860 C,硬度840-860 C,硬度为61-63 Hrc,以下温度150-1-1-20-1-170 c 150 c,以61-63 Hrc,速度150 c。
