alloy-steel; alloy-treated steel; fine steel; steel alloy; alloy steel (【技】在碳素钢的基础上通过添加适量的一种或多种合金元素而获得的铁碳合金。与碳素钢相比，合金钢具有较高的强度、韧性、淬透性、耐磨性、耐蚀性、耐低温性、耐热性等特殊性能。按用途合金钢分为：建筑结构用钢、机械结构用钢、工具钢及特殊性能钢。: ① The most important use of chromium is in alloy steels, where it confers increased hardness after heat-treatment. 铬最重要的用途是用于合金钢，它能提高合金钢热处理后的硬度。 ②Alloy steels are basically carbon steels with additional alloy elements added to alter the characteristics and bring about a predictable change in the mechanical properties. 从本质上说，合金钢是通过添加合金元素改变其特性并产生预期力学性能变化的碳钢。) |
