与普通碳素结构钢相比,优质碳素结构钢的硫、磷和其他非金属夹杂物含量较低。根据不同的碳含量和用途,这种钢可以大致分为三类:①小于0。25%C是低碳钢,尤其是低于0的碳。10% 08F、08Al等。广泛用作汽车、罐头等拉深件。由于它们良好的深冲压性和焊接性。20G是制造普通锅炉的主要材料。此外,低碳钢也被广泛用作机械制造中的渗碳钢。②0。25 ~ 0。60%C是中碳钢,主要用于淬火和回火状态,为机械制造业制造零件。③大于0。6%C是高碳钢,主要用于制造弹簧、齿轮、辊子等。根据锰含量的不同,可分为普通锰含量( 0.25 ~ 0。8 % )和高锰含量( 0。7 ~ 1。0 %和0。9 ~ 1。2 % )两个钢铁集团。锰可以提高钢的淬透性,强化铁素体,提高钢的屈服强度、抗拉强度和耐磨性。通常,高锰含量钢的品牌标有“Mn”,如15Mn和20Mn,以区别于正常锰含量的碳钢。
