合金钢和碳钢的区别及钢铁元素分析仪器的介绍 合金钢和碳钢的区别及钢铁元素分析仪器的介绍   合金钢与碳钢相比含有较多其他元素。合金钢是指钢中除含硅和锰作为合金元素或脱氧元素外,还含有其他合金元素(如铬、镍、钼、钒、钛、铜、钨、铝、钴、铌、锆和其他元素等),有的还含有某些非金属元素(如硼、氮等)的钢。根据钢中合金元素含量的多少,又可分为低合金钢,中合金钢和高合金钢。  而碳钢主要指力学性能取决于钢中的碳含量,而1般不添加大量的合金元素的钢,有时也称为普碳钢或碳素钢。  碳钢也叫碳素钢,含炭量WC小于2%的铁碳合金。碳钢除含碳外1般还含有少许的硅、锰、硫、磷按用处可以把碳钢分为碳素结构钢、碳素工具钢和易切削结构钢3类。碳素结构钢又分为建筑结构钢和机器制造结构钢两种按含碳量可以把碳钢分为低碳钢(WC ≤ 0.25%),中碳钢(WC0.25%——0.6%)和高碳钢(WC>0。
