    36Mn2V鋼石油套管的亞溫淬火強(qiáng)韌化處理工藝

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

    • 摘要: 探討了在線?；?6Mn2V鋼Φ114.3 mm×6.35 mm石油套管熱處理工藝,并進(jìn)行了石油套管的亞溫淬火工藝試驗(yàn)。試驗(yàn)結(jié)果表明,合理的亞溫淬火工藝可以獲得綜合力學(xué)性能良好的石油套管,并且完全滿足美國API Spec 5CT標(biāo)準(zhǔn)中規(guī)定的N80鋼級(jí)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.
