一、前言在室外大气条件下长期使用的各种钢材,除了要求具有优良的机械性能、加工成型性和焊接性能外,还应具有优良的耐大气腐蚀性能。Cor-Ten 钢正是这种兼有优良的耐大气腐蚀性能的低合金高强度钢。早在二十世纪初期,欧美一些国家就开始研究以铜、磷为主体的耐大气腐蚀钢,根据文献,1929年美国材料试验协会(ASTM)发表了 Kenaolall 和 Taylerson 的研究论文,证实了铜、磷可以提高钢材的耐大气腐蚀性。1930年美国联邦钢铁公司应用研究
I. Foreword In the outdoor atmospheric conditions long-term use of a variety of steel, in addition to require excellent mechanical properties, processing and welding properties, but also should have excellent atmospheric corrosion resistance. Cor-Ten steel is this low-alloy high-strength steel with excellent atmospheric corrosion resistance. As early as the early twentieth century, some countries in Europe and the United States started to study atmospheric corrosion-resistant steels mainly composed of copper and phosphorus. According to the literature, a research paper by Kenaolall and Taylerson published by the American Society for Testing and Materials (ASTM) in 1929 confirmed that copper, Phosphorus can improve the atmospheric corrosion resistance of steel. 1930 US Federal Iron and Steel Company Applied Research
