[1] Y15為易切削結(jié)構(gòu)鋼,通過(guò)提高鋼中的硫和錳的含量,形成大量的硫化錳夾雜物,切削時(shí)鐵屑極易斷開(kāi),可提高零件表面質(zhì)量,并能以更快的切削速度和更深的進(jìn)刀量加工,從而提高生產(chǎn)效率和節(jié)約生產(chǎn)成本。低碳易切削鋼主要用來(lái)制造對(duì)強(qiáng)度要求不高,但粗糙度要求較高的零件,如螺絲、螺桿、螺帽、管接頭、連接螺栓等。中碳易切削鋼Y35可用于強(qiáng)度要求較高,且不易加工的零件,如紡織機(jī)、計(jì)算機(jī)上的零件。低碳易切削鋼一般在熱軋或冷拉狀態(tài)下使用,也可表面滲碳處理;中碳易切削鋼一般在熱處理后使用?;瘜W(xué)成分C :0.10-0.18P:0.05-0.10S :0.23-0.33Mn :0.80-1.20Si :≤0.15力學(xué)性能抗拉強(qiáng)度 σb (MPa):(熱軋)390~540;(冷拉)鋼材厚度或直徑 8~20時(shí):530~755; >20~30時(shí):510~735; >30時(shí):490~685,伸長(zhǎng)率 δ5 (%):(熱軋)≥22;(冷軋)≥7.0斷面收縮率 ψ (%):(熱軋)≥36
