AISI（美国钢铁学会标准）是由美国钢铁学会制定的金属材料行业技术规范，属于美国专/行业标准体系的重要组成部分。 该标准体系通过三位数字编码系统对钢材进行分类，例如201、304等典型牌号，并与ASTM标准在技术内涵上具有等效性。 For more than 80 years, the steel industry has maintained a construction codes and standards program through the American Iron and Steel Institute (AISI) to address the regulations and laws governing the entire construction market. 有理由相信，SAE钢等级最初可能直接引用了AISI的钢等级编码规则体系，SAE/AISI的相关标准或规范中，通常可以发现，相同的钢代号对应的化学成分的规定是完全一致的。 这套编码通常由4位数字组合组成，合金元素由前2位数字表示，碳含量由后2位数字表示。 Sep 18, 2024 · AISI (American Iron and Steel Institute) is a trade association founded in 1855 that represents the steel industry in North America. engineersedge.
