A283碳钢板/板材
-产品描述
1. 化学成分
碳钢的主要成分是铁(Fe)和碳(C)，其他元素含量较低。分类如下：
类型 碳(C) 锰(Mn) 硅(Si) 硫(S) 磷(P)
低碳钢 0.05%–0.25% 0.3%–0.6% ≤0.3% ≤0.05% ≤0.04%
中碳钢 0.25%–0.60% 0.6%–1.0% ≤0.4% ≤0.04% ≤0.04%
高碳钢 0.60%–1.0% 0.3%–0.9% ≤0.4% ≤0.03% ≤0.03%
备注：
硫(S)和磷(P)是杂质元素。优质碳钢需要严格控制其含量(如S ≤ 0.03%，P ≤ 0.03%)。
锰(Mn)增强强度和韧性，其含量根据碳含量调整。
2. 机械性能
机械性能与碳含量和热处理条件密切相关：
参数 低碳钢(如Q235) 中碳钢(如45#) 高碳钢(如T8)
抗拉强度 300–500 MPa 500–800 MPa 600–1000 MPa
屈服强度 200–300 MPa 300–550 MPa 400–800 MPa
延伸率(%) 20%–35% 10%–20% 5%–15%
硬度(HB) 120–160 160–250 200–350
备注：
低碳钢：优异的塑性、焊接性和成型性，但强度较低。常用于结构件(如建筑、桥梁)。
中碳钢：淬火回火后性能均衡。用于机械零件(齿轮、轴)。
高碳钢：高硬度和耐磨性但脆性大。需热处理(如球化退火)改善切削性。用于工具、弹簧等。
3. 典型应用
低碳钢板：建筑结构、汽车车身板、管道、容器。
中碳钢板：机械零件、连杆、齿轮、高强度螺栓。
高碳钢板：切削工具、弹簧、耐磨件、铁轨。
