Heat Treatment

锤后一般退火:加热温度830-850度,炉冷至550度以下出炉空冷,退火后硬度229HBW。

锤后等温退火工艺:加热温度830-850度,等温温度700-720度,炉冷至550度出炉空冷,硬度≤229HBW,退火金相组织均为细粒状珠光体+碳化物。

在淬火和低温回火(960~980度淬油,200~300度回火)后含有质量分数约8%~10%的碳化物,质量分数为15%~20%的残留奥氏体。回火温度为150~170度,硬度为62~63HRC;回火为190~210度,硬度为58~60HRC。

General annealing after hammering: the heating temperature is 830-850 ℃, the furnace is cooled to below 550 ℃, the furnace is air cooled, and the hardness after annealing is 229hbw.

Isothermal annealing process after hammering: heating temperature 830-850 ℃, isothermal temperature 700-720 ℃, furnace cooling to 550 ℃, outgoing air cooling, hardness ≤ 229hbw, annealing metallographic structure is fine-grained pearlite + carbide.

After quenching and low-temperature tempering (960 ~ 980 degrees oil quenching, 200 ~ 300 degrees tempering), it contains about 8% ~ 10% carbide and 15% ~ 20% retained austenite. The tempering temperature is 150 ~ 170 ℃ and the hardness is 62 ~ 63hrc; Tempering is 190 ~ 210 degrees and hardness is 58 ~ 60HRC.
