    • The heat- and creep-resistant steel has a martensitic microstructure produced by a heat-treatment process. The composition of the steel in percent by weight is as follows:0.001-0.05 of carbon0.05-0.5 of silicon0.05-2.0 of manganese0.05-2.0 of nickel8.0-13.0 of chromium0.05-1.0 of molybdenum1.00-4.0 of tungsten0.05-0.5 of vanadium0.01-0.2 of niobium2.0-6.5 of cobalt0.1-0.3 of nitrogen,the remainder being iron and unavoidable impurities. Such a steel can be produced by forging, casting or by powder-metallurgical means. Components fabricated from this steel show a high strength and ductility at room temperature and are distinguished at temperatures of 600.degree. C. and higher by a very high creep strength and an unusually high oxidation resistance. They can therefore be used with advantage as mechanically and thermally highly stressed components in steam- and/or gas-operated power stations.
    • 耐热和耐蠕变钢具有通过热处理工艺生产的马氏体组织。 钢的组成为重量百分比如下:0.05-0.5的碳0.05-0.5的硅0.05-2.0的锰0.05-2.0的镍8.0-13.0的铬0.05-1.0的钼1.00-4.0的钨0.05- 0.5的钒0.01-0.2的铌2.0-6.5的钴0.1-0.3的氮,其余的是铁和不可避免的杂质。 这种钢可以通过锻造,铸造或通过粉末冶金方式生产。 由该钢制成的部件在室温下显示出高强度和延展性,并且在600℃以上的温度下通过非常高的蠕变强度和异常高的抗氧化性来区分。 因此,它们可以在蒸汽和/或气体操作的发电站中作为机械和热应力高的部件被有利地使用。
