11045是指常用中碳调质结构钢。
  化学成分:  C0.42~0.50Si0.17~0.37Mn0.50~0.80Cr:≤0.25Ni:≤0.30Cu:≤0.25
2
、该钢冷塑性一般,退火、正火比调质时要稍好,具有较高的强度和较好的切削加工性,经适当的热处理以后可获得一定的韧性、塑性和耐磨性,材料来源方便。
3
1045钢适合于氢焊和氩弧焊,不太适合于气焊。焊前需预热,焊后应进行去应力退火。
4
1045号钢密度7.85g/cm3,弹性模量210GPa,泊松比0.269。推荐热处理温度:正火850,淬火840,回火600

5
1045号钢为优质碳素结构用钢,硬度不高易切削加工,模具中常用来做模板,梢子,导柱等,但须热处理。
6
1045号钢淬火后没有回火之前,硬度大于HRC55(最高可达HRC62)为合格。实际应用的最高硬度为HRC55(高频淬火HRC58)
7
1045号钢不要采用
渗碳淬火的热处理工艺。
