●特性及适用范围:
强度、韧性均高于20Cr钢,淬火后表面硬度很高,韧性好,淬透性较低。用于表面要求高硬度和耐磨、心部有非常大强度而断面又不大的渗碳零件,如齿轮、活塞销、小轴、分配轴、顶杆、汽门推杆及汽轮机上在 300~500 ℃下工作的耐热螺母及垫圈,非腐蚀介质中工作的高压管道等。
●化学成份:
碳 C :0.17~0.23
硅 Si:0.17~0.37
锰 Mn:0.50~0.80
硫 S :允许残余含量≤0.035
磷 P :允许残余含量≤0.035
铬 Cr:0.80~1.10
镍 Ni:允许残余含量≤0.030
铜 Cu:允许残余含量≤0.030
钒 V :0.10~0.20
●力学性能:
抗拉强度 σb (MPa):≥835(85)
屈服强度 σs (MPa):≥590(60)
伸长率 δ5 (%):≥12
断面收缩率 ψ (%):≥45
冲击功 Akv (J):≥55
冲击韧性值 αkv (J/cm2):≥69(7)
硬度 :≤197HB
试样尺寸:试样毛坯尺寸为15mm
●热处理规范及金相:
热处理规范:淬火: 初次
880℃,第二次800℃,水冷、油冷;回火200℃,水冷、空冷。
●交货状态:以热处理(正火、退火或高温回火)或不热处理状态交货,交货状态应在合同中注明。
