摘要
研究结果表明 ,含 0 .0 18%N的低氮 0Cr13Ni4Mo马氏体不锈钢未出现中温回火脆性 ,含 0 .0 5 4%N的高氮钢有中温回火脆性出现 ,经 6 0 0℃高温回火后可获得高的强韧性配合和极高的 - 6 0℃低温冲击韧性。
The research results showed that the annealing brittleness of low nitrogen (0.018%N) martensitic stainless steel 0Cr13Ni4Mo has not been found: the high nitrogen (0.054%N) steel 0Cr13Ni4Mo had middle temperature (475 ℃) annealing brittleness, but with 600℃ tempering, the steel had excellent combination of strength\|toughness and supper toughness at -60 ℃.
