淬灭温度主要根据高铬铸铁的耐磨衬里.下舌下钢通常加热至AC3上方30〜50度，而Eutectioid钢和低甲状腺皮质钢的加热，而在AC1上方则加热到30〜50度，以及在某些情况下为50〜70级的温度。亚素下钢钢低于AC3，那么钢目前尚未完全适应，并且某些未转化的铁素体存在，并且铁岩在淬火后仍处于淬火结构中.屈光度.屈光石的硬度很低，因此在quench液后的硬度也无法满足其他属性，如果需要}属性，如果属性也无法构成{}的属性{ is heated to the Ac3 temperature for quenching, the austenite grain will be significantly larger, thus damaging the properties after quenching.The eutectoid steel was heated above Ac1 at 30 ~ 50℃.After quenching, only a few residual austenite particles were found in vitro, and the structure was small carbide particles evenly distributed on the lamellar martensite矩阵{.这种组织具有高硬度，良好的耐磨损性和相对较低的耐刺{.，低甲状腺类钢的淬火温度不能低于AC1的淬火温度，因为此时钢目前尚未被降低到{22}} .的温度略高的温度，并且在一个温度下的温度不高，并且在一个温度下，均高于Pear的温度，并且均高于pear的温度，并不是在温度下的温度，并且均不高。 dissolves into austenite.The austenite grains were fine and the carbon mass fraction was higher than that of eutectoid.If the temperature continues to rise, the secondary cementite will continue to dissolve into austenite, resulting in the continuous growth of austenite grains and the increasing carbon concentration, which will lead to the increase of quenching deformation tendency, quenching微结构微裂纹和勃tlenesenes .同时，由于高奥斯丁碳含量，淬火后残留的奥氏体的量增加，降低了耐磨性衬里的硬度和磨损性.}}}}}}}}}}}}
因此，超类钢钢的淬火加热温度不适合高于AC1，并且加热到完全奥氏体化的ACM或更高的温度更不适当
