Y15易切削钢
●特性及适用范围:
是 S-P复合高硫、低硅易切削钢。切削性明显高于Y12,生产效率比Y12钢提高30~50%,特别是攻丝时,丝锥寿命比 Y12提高两倍以上,常用于制造不重要的标准件中,如螺栓、螺母、管接头、弹簧座等。
●化学成份:
碳 C :0.10~0.18
硅 Si:≤0.15
锰 Mn:0.80~1.20
硫 S :0.23~0.33
磷 P :0.05~0.10
●力学性能:
抗拉强度 σb (MPa):(热轧)390~540; (冷拉)钢材厚度或直径 8~20时:530~755; >20~30时:510~735; >30时:490~685
伸长率 δ5 (%):(热轧)≥22;(冷轧)≥7.0
断面收缩率 ψ (%):(热轧)≥36
硬度 :(热轧)≤170HB;(冷拉)152~217HB
●热处理规范及金相组织:
●交货状态:以热轧或冷拉状态交货,交货状态应在合同中注明。
