摘　　要：实验研究了SKS51钢在650～900℃的脱碳特性及其对淬硬性的影响。结果表明:随温度升高及保温时间的延长,脱碳层深度增加,尤其在800℃以上时,脱碳现象明显加剧;脱碳现象对钢的淬硬性有明显影响,随脱碳层深度增加,钢的硬度降低。Decarburizing characteristic and its effect on steel SKS51 between 650 ℃ and 900℃ were investigated. The results show that the decarburization depth increases with the increase of temperature or holding time. There is significant increase if temperature is above 800 ℃. Decarburization has great influence on hardenability. The hardness of the steels decreases with the increase of the decarburization depth.
