补充资料：低碳钢
分子式：
CAS号：
性质：含碳量小于0.25％的碳素钢：有时还含有少量锰(0.70％～1.00％)如20Mn，25Mn等。按质量分为普通钢和优质钢，前者的硫、磷含量分别不大于0.050％和0.045％，后者分别不大于0.030％～0.040％和0.035％～0.040％。低碳钢的特点是低强度和高塑性、高韧性及良好的加工成形性和焊接性能。适宜制作形状复杂和需要焊接的零件和构件。普通低碳钢一般不热处理而直接使用。优质低碳钢或不作热处理，或作表面硬化(如渗碳)处理。低碳钢的常用性能范围是：σb为294～490MPa，δ为25％～40％，HB为100～150。经冷加工后可提高强度、降低塑性和韧性。主要制作钢丝、钢板等，作建筑材料和结构件，表面硬化处理的优质低碳钢可制成各种中小型机械零件、齿轮、轴等。参见碳素结构钢。
