摘　　要：对河冶M35钢与国外S705(该企业的M35钢牌号)钢进行了化学成分、气体及夹杂、低倍组织、碳化物及热处理性能等进行了对比。结果表明:S705钢的碳含量偏高,并且超出国标要求范围,M35钢的氮、氢含量较低、夹杂物含量较少,并且碳化物颗粒细小一些。从综合分析看,河冶M35钢质量水平优于国外S705钢。It is compared the M35 steel of Heye and the foreign S705 steel （M35 in this enterprise） in chemical composition, air and inclusion, macro structure, carbide and heat treatment performance. It is showed that the carbon content of S705 is a little higher and over the Chinese national standard; the nitrogen and hydrogen content of M35 is lower, inclusion less, grain size of carbide thinner. In comprehensive, M35 of Heye is superior to foreign S705.
