摘　　要：阐述了元素硫、氧、钙、锶对钢性能的影响 ,介绍了H2 超低硫耐热钢 (3Cr2 5Ni10 )化学成分选择的依据。叙述了H2 钢的熔炼工艺及其主要性能的测试结果。结果表明H2 -2 耐热钢 (含S <0 .0 0 1% ,Ca 0 .0 0 3%～ 0 .0 0 4 % )的高温抗氧化性能、高温持久强度和热疲劳性能好于H1钢 ,远好于H0 钢 ;其生产成本稍低于H1钢 ,远低于H0 钢。性能比较表明H2 -2 钢完全可以替代H0 钢用于制作高温还原罐 ,预计的使用寿命比H0 和H1钢高 ,且经济效益十分显著。Effect of sulphur oxygen stronium and cacium on properties of the heat-resisting steel is discussed. The chemical composition of the heat-resisting steel H 2 (3Cr25Ni10) has been designed. The smelting technology of H 2 is reviewed. The properties of H 2 has been determined. The results are that the properties of H 2-2 with S<0.001% Ca=0.003%～0.004% are better than H 1 and H 0, The production cost of H 2-2 is lower than H 1 and H 0, H 2-2 can takes the place of H 0 and that is used for manufacturing high temperature reactor.
