在壓力加工、鑄造、焊接、熱處理、切削加工和其他工藝過(guò)程中，制品可能產(chǎn)生內(nèi)應(yīng)力。多數(shù)情況下，在工藝過(guò)程結(jié)束后，金屬內(nèi)部將保留一部分殘余應(yīng)力。殘余應(yīng)力可導(dǎo)致工件破裂、變形或尺寸變化，殘余應(yīng)力也提高金屬化學(xué)活性，在殘余拉應(yīng)力作用下特別容易造成晶間腐蝕破裂。因此，殘余應(yīng)力將影響精密無(wú)縫鋼管的使用性能或?qū)е鹿ぜ^(guò)早失效。

</p> <p> 去應(yīng)力退火并不能完全精密無(wú)縫鋼管內(nèi)部的殘余應(yīng)力，而只是大部分。要使殘余應(yīng)力徹底，需將精密無(wú)縫鋼管加熱至更高溫度。在這種條件下，可能會(huì)帶來(lái)其他組織變化，危及精密無(wú)縫鋼管的使用性能。 </p></div><p><img
