Y15易切削鋼
●特性及適用范圍:
是 S-P復(fù)合高硫、低硅易切削鋼。切削性明顯高于Y12,生產(chǎn)效率比Y12鋼提高30~50%,特別是攻絲時,絲錐壽命比 Y12提高兩倍以上,常用于制造不重要的標準件中,如螺栓、螺母、管接頭、彈簧座等。
●化學(xué)成份:
碳 C :0.10~0.18
硅 Si:≤0.15
錳 Mn:0.80~1.20
硫 S :0.23~0.33
磷 P :0.05~0.10
●力學(xué)性能:
抗拉強度 σb (MPa):(熱軋)390~540; (冷拉)鋼材厚度或直徑 8~20時:530~755; >20~30時:510~735; >30時:490~685
伸長率 δ5 (%):(熱軋)≥22;(冷軋)≥7.0
斷面收縮率 ψ (%):(熱軋)≥36
硬度 :(熱軋)≤170HB;(冷拉)152~217HB
●熱處理規(guī)范及金相組織:
●交貨狀態(tài):以熱軋或冷拉狀態(tài)交貨,交貨狀態(tài)應(yīng)在合同中注明。
