研究了00Cr22Ni5Mo3N钢的热扭转性能，结果表明，通过对化学成分和扭转温度的合理控制，可以使00Cr22Ni5Mo3N钢获得良好的热塑性，并使其变形抗力小于1Cr18Ni9Ti钢。根据试验结果制订了生产工艺，采用热穿孔工艺成功试制出00Cr22Ni5Mo3N钢大口径厚壁无缝管。

Ｔhe hot torsion ductility of 00Cr22Ni5Mo3N was studied.The result showed that with proper control of steel composition and at proper torsion temperature,00Cr22Ni5Mo3N is quite ductile with a deformation resistance lower than that of 1Cr18Ni9Ti. According to the test result, the technology of piercing was developed and 00Cr22Ni5Mo3N large size seamless pipes were produced in trial.
