淬滅溫度主要根據高鉻鑄鐵的耐磨襯裡.下舌下鋼通常加熱至AC3上方30〜50度，而Eutectioid鋼和低甲狀腺皮質鋼的加熱，而在AC1上方則加熱到30〜50度，以及在某些情況下為50〜70級的溫度。亞素下鋼鋼低於AC3，那麼鋼目前尚未完全適應，並且某些未轉化的鐵素體存在，並且鐵岩在淬火後仍處於淬火結構中.屈光度.屈光石的硬度很低，因此在quench液後的硬度也無法滿足其他屬性，如果需要}屬性，如果屬性也無法構成{}的屬性{ 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矩陣{.這種組織具有高硬度，良好的耐磨損性和相對較低的耐刺{.，低甲狀腺類鋼的淬火溫度不能低於AC1的淬火溫度，因為此時鋼目前尚未被降低到{22}} .的溫度略高的溫度，並且在一個溫度下的溫度不高，並且在一個溫度下，均高於Pear的溫度，並且均高於pear的溫度，並不是在溫度下的溫度，並且均不高。 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微結構微裂紋和勃tlenesenes .同時，由於高奧斯丁碳含量，淬火後殘留的奧氏體的量增加，降低了耐磨性襯裡的硬度和磨損性.}}}}}}}}}}}}
因此，超類鋼鋼的淬火加熱溫度不適合高於AC1，並且加熱到完全奧氏體化的ACM或更高的溫度更不適當
