摘　　要：为了获得27Cr Mo钢种升级为P110钢级石油套管的最佳热处理工艺,研究了热处理工艺对27Cr Mo钢组织和硬度的影响。结果表明,对27Cr Mo钢进行调质处理,得到回火索氏体,具有良好的综合力学性能,并且满足石油工业套管性能的需求。另外,将调质处理后的金相组织与原始的相比较,也能够证明性能得到提高。通过不同回火温度得到的硬度变化曲线,并结合得到的金相图,确定P110钢级热处理工艺。In order to get the optimal heat treatment process of upgrading 27 Cr Mo steel to P110 oil casing,we study the effect of heat treatment process on the microstructure and hardness of 27 Cr Mo. The results show that the tempered sorbite got by the quenching and tempering of 27 Cr Mo,has good comprehensive mechanical properties,and can meet the needs of the oil industry casing performance. In addition,the metallographic structure after quenching and tempering is compared with the original one,which improving peformance can be proved too. Heat treatment technology of P110 steel grade is determined by the hardness change curves of different tempering temperature combining with the metallgraphic diagram.
