硅鋼片是電機(jī)和變壓器制造中用量很大的鋼材，按化學(xué)成分硅鋼可以分為低硅鋼和高硅鋼。低硅鋼含硅量wsiO％～2.5％，主要用來制造電機(jī)；高硅鋼含硅量wsiO％～4.5％，一般用來制造變壓器。它們的含碳量wcO．06％～0.08％。<br /> 16鋼軌鋼鋼軌主要承受機(jī)車車輛的壓力及沖擊載荷，因此，要求有足夠的強(qiáng)度和硬度及一定的韌性。通常采用的鋼軌鋼是平爐和轉(zhuǎn)爐冶煉的碳素鋼，這種鋼含碳wc0.6％。0.8％，屬于中碳鋼和高碳鋼，但鋼中含錳量WMn較高，在O．6％一1.1％的范圍內(nèi)。<br /> 近年來，已廣泛采用普通低合金鋼鋼軌，如高硅軌、中錳軌、含銅軌、含鈦軌等。普通低合金鋼軌比碳素鋼軌耐磨、耐腐蝕，使用壽命有很大。 </div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/135/1250/202402220325241821.jpg" title="角鋼、角鋼廠家-質(zhì)量保證"><br></p><p><img
