摘要
针对27SiMn的厚壁无缝钢管淬透性较差,热处理后钢管性能稳定性较差,两端差异性较大,强度、硬度匹配性较差等问题,通过调整淬火温度、淬火保温时间,回火温度及保温时间,可以改善产品的状态,提高了产品强度,降低了硬度。
In order to deal with the problems of the poor hardenability, unsatisfactory property stabilityafter heat treatment, big difference at pipe ends and mismatching of strength and hardness of 27SiMnthick-walled seamless steel pipe, measures were taken by adjusting quenching temperature, quenchingholding time, tempering temperature and tempering holding time so as to improve product state, increaseproduct strength and lower hardness.
