    • Disclosed is an alloy steel of high corrosion resistance to hot molten salts containing chlorides and/or alkali oxides. The alloy steel is manufactured from a composition comprising 20-40 weight % of Ni, 0-8 weight % of Cr, 0.05 weight % or less of C, 0.5 weight % or less of Si, 1.0 weight % or less of Mn, 0.05 weight % or less of S, and the balance of Fe to total weight. With a low Cr content, the alloy steel is superb in the corrosion resistance to chloride and/or alkali oxide-containing molten salts, including LiCl—Li2O. Also, the alloy steel shows stable corrosion resistance to molten salts even at high temperature as well as low temperature in addition to being superior to workability. Thus, the alloy steel can be processed into plates, bars or pipes which are used for structural materials and structural components for treating molten salts.
    • 公开了对含有氯化物和/或碱金属氧化物的热熔盐具有高耐腐蚀性的合金钢。 该合金钢由以下组成制成,该组合物包含20-40重量%的Ni,0-8重量%的Cr,0.05重量%以下的C,0.5重量%以下的Si,1.0重量%以下的Mn,0.05 重量%以下的S,余量为Fe与总重量的比例。 对于低Cr含量,合金钢对含氯化物和/或碱金属氧化物的熔融盐(包括LiCl-Li 2 O)的耐腐蚀性极佳。 此外,即使在高温以及低温下,合金钢也显示出对熔融盐的耐腐蚀性,而且优于加工性。 因此,合金钢可以加工成用于结构材料的板,棒或管,以及用于处理熔盐的结构部件。
