化学成分性能作用
1.1.镍;能提高钢的强度和韧性,提高淬透性.含量高时,可显著改变钢和合金的一些物理性能,提高钢的抗腐蚀能力.
1.2.铬;能提高钢的淬透性和耐磨性,能改善钢的抗腐蚀能力和抗氧化作用.
1.3.钒;能细化钢的晶粒组织,提高钢的强度,韧性和耐磨性.当它在高温熔入奥氏体时,可增加钢的淬透性; 反之,当它在碳化物形态存在时,就会降低它的淬透性
1.4.钛:能细化钢的晶粒组织,从而提高钢的强度和韧性.在不锈钢中,钛能消除或减轻钢的晶间腐蚀现象.
1.5.硅;它可以提高钢的硬度,但是可塑性和韧性下降,电工用的钢中含有一定量的硅,能改善软磁性能. .2冷轧卷生产流程:热轧卷-压延-退火-平整-冷轧卷。 .3常见硬度:软态,1/4、1/2H、3/4H、H,EH等 3.1 硬度是材料弹性、塑性、强度和韧性等力学性能的综合指标。
