低溫回火又稱“消除應力回火”?；鼗饻囟确秶鸀?50-250攝氏度，回火后的組織為回火馬氏體。鋼具有高硬度和高耐磨性，但內(nèi)應力和脆性降低。經(jīng)滲碳和表面淬火的零件，回火后的硬度一般為58-64HRC。 </p> <p> 鋼球回火時間： </p> <p> 回火時間應包括按工件截面均勻地達到回火溫度所需加熱時間以及按M參數(shù)達到要求回火硬度完成組織轉(zhuǎn)變所需的時間，如果考慮內(nèi)應力的消除，則尚應考慮不同回火溫度下應力弛豫所需要的時間。 </p> <p> <br /> </p> <p> 對以應力弛豫為主的低溫回火時間應比表列數(shù)據(jù)長，長的可達幾十小時。對二次硬化型高合金鋼，其回火時間應根據(jù)碳化物轉(zhuǎn)變過程通過試驗確定。當含有較多殘余奧氏體，而靠二次淬火消除時，還應確定回火次數(shù)。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
