日本钢铁公司已设计出一种用于汽车排气系统的耐热性能优良的低铬素体不锈钢。 耐热性正越来越成为应用于汽车排气系统材料的一项重要性能。耐热性的提高,随之而来就能采用减少排气系统管路的壁厚以改
Nippon Steel has designed a low-chromium body stainless steel for heat-resistant automotive exhaust systems. Heat resistance is increasingly becoming an important property of materials used in automotive exhaust systems. Increased heat resistance, followed by the exhaust pipe can be used to reduce the wall thickness to change
