【试样毛坯尺寸】
25mm
【热处理】
淬火加热温度(℃):850;冷却剂:油
回火加热温度(℃):600;冷却剂:水、油
【力学性能】
抗拉强度(σb/MPa):≧980
屈服点(σs/MPa):≧785
断后伸长率(δ5/%):≧10
断面收缩率(ψ/%):≧45
冲击吸收功(Aku2/J):≧63
布氏硬度(HBS100/3000)(退火或高温回火状态):≦217
调质处理后具有良好的综合力学性能,淬透性较好,回火稳定性较高。大多在调质状态下使用[2]。
常用于制造重载、截面较大的齿轮轴、齿轮、大卡车的后桥半轴、轴、偏心轴、连杆、汽轮机的类似零件,还可代替40CrNiMo使用。[3][4][5]
