| 中文摘要: |
| 针对35CrMo钢石油套管调质处理后低温冲击韧性偏低且不稳定的问题,对35CrMo钢进行“零保温”热处理试验.结果表明:与常规调质热处理相比,“零保温”热处理的35CrMo钢获得非常细小的回火索氏体,在不降低强度的前提下能有效改善其低温韧性.因节省了保温时间,能耗可较大程度降低. |
| 英文摘要: |
| “Zero insulation” heat treatment was done to 35CrMo steel to solve the problem of low toughness and the instability of 35CrMo steel oil casting after treated by quenching and tempering.The results show that 35CrMo steel treated by “zero insulation” heat treatment can obtain very fine sorbite compared with the traditional heat treatment,which can improve remarkably the low temperature toughness of the steel without reducing the strength.At the same time,the “zero insulation” heat treatment can reduce the energy consumption to a greater extent as it saves the holding time. |
