优良的强度和硬度,要比优良的耐腐蚀性和装饰性更引人注意,这是由美国Allegheny Ludlum钢公司的冶金学家Paul和James获得专利的新型“非稳定”奥氏体不锈钢的主要优点。这种标号为12Cr—7.5Mn—2.0Ni—0.1N—0.04C的钢,是由于它的原始奥氏体显微组织在冷加工时迅速转化成马氏体之故。
Excellent strength and hardness are more attractive than excellent corrosion resistance and decorativeness, which is the main new “unstable” austenitic stainless steel patented by the metallurgists Paul and James of Allegheny Ludlum Steel Co. of the United States advantage. This steel, designated 12Cr-7.5Mn-2.0Ni-0.1N-0.04C, is due to the rapid transformation of its original austenitic microstructure into martensite during cold working.
