style="text-indent:25px">圓鋼按化學(xué)成分分類(lèi)有低碳鋼、中碳鋼和高碳鋼。中碳鋼：碳量0.25%～0.60%的碳素鋼。有沸騰鋼等多種產(chǎn)品。除碳外還可含有少量錳（0.70%～1.20%）。按產(chǎn)品質(zhì)量分為普通碳素結(jié)構(gòu)鋼和較好碳素結(jié)構(gòu)鋼。熱加工及切削性能良好，焊接性能較差。強(qiáng)度、硬度比低碳鋼高，而塑性和韌性低于低碳鋼?？刹唤?jīng)熱處理，直接使用熱軋材、冷拉材，亦可經(jīng)熱處理后使用。淬火、回火后的中碳鋼具有良好的綜合力學(xué)性能。能夠達(dá)到的較高硬度約為HRC55(HB538），σb為600～1100MPa。所以在中等強(qiáng)度水平的各種用途中，中碳鋼得到較普遍的應(yīng)用，除作為建筑材料外，還大量用于制造各種機(jī)械零件。合金圓鋼在進(jìn)行生產(chǎn)加工時(shí)以便確保其應(yīng)用品質(zhì)，會(huì)對(duì)它開(kāi)展調(diào)質(zhì)處理生產(chǎn)加工。青島CR12圓鋼銷(xiāo)售</p><p
