36Mn2V钢石油套管的亚温淬火强韧化处理工艺

Strengthening/Toughening Via Sub-temperature Quench Treatment Process for 36Mn2V Oil Casing

摘要: 探讨了在线常化的36Mn2V钢Φ114.3 mm×6.35 mm石油套管热处理工艺,并进行了石油套管的亚温淬火工艺试验。试验结果表明,合理的亚温淬火工艺可以获得综合力学性能良好的石油套管,并且完全满足美国API Spec 5CT标准中规定的N80钢级性能要求。

Abstract: Discussed is the on-line normalization heat treatment of the Ф114.3 mm×6.35 mm 36Mn2V casing, and test of sub-temperature quench process thereof as carried out. The test result shows that the subtemperature quench process enables the said casing to have satisfactory comprehensive mechanical properties and meet relevant requirements for the N80 steel grade as specified in API Spec. 5CT.
