style="font-size:14px;">由于球墨鑄鐵的球狀石墨微觀結(jié)構(gòu)，在減弱振動(dòng)能力方面，球墨鑄鐵優(yōu)于鑄鋼，因此更加有利于降低應(yīng)力。選擇球墨鑄鐵的一個(gè)重要的原因在于球墨鑄鐵比鑄鋼成本低。球墨鑄鐵的低成本使得這種材料更加受歡迎，鑄造效率更高，也較少了球墨鑄鐵的機(jī)加工成本。</span> </p> <p> <span style="font-size:14px;">球墨鑄鐵的強(qiáng)度和鑄鋼的強(qiáng)度是可比的。球墨鑄鐵具有更高的屈服強(qiáng)度，其屈服強(qiáng)度蕞低為40k，而鑄鋼的屈服強(qiáng)度只有36k。在大部分市政應(yīng)用領(lǐng)域，昆明井蓋定制，昆明井蓋定制，如：水，昆明井蓋定制、鹽水、蒸汽等，球墨鑄鐵的耐腐蝕性和抗氧化性都超過鑄鋼。</span>

style="font-size:14px;">球墨鑄鐵井蓋是球墨鑄鐵產(chǎn)品的一種，球墨鑄鐵通過球化和孕育處理得到球狀石墨，有效地提高了鑄鐵的機(jī)械性能，特別是提高了塑性和韌性，從而得到比碳鋼還高的強(qiáng)度。球墨鑄鐵是20世紀(jì)五十年展起來的一種強(qiáng)度高的鑄鐵材料，其綜合性能接近于鋼，正是基于其優(yōu)異的性能，已成功地用于鑄造一些受力復(fù)雜，強(qiáng)度、韌性、耐磨性要求較高的零件。球墨鑄鐵已迅速發(fā)展為只次于灰鑄鐵的、應(yīng)用十分普遍的鑄鐵材料。所謂“以鐵代鋼”，主要指球墨鑄鐵。生鐵是含碳量大于2%的鐵碳合金，工業(yè)生鐵含碳量一般在，并含C、SI、Mn、S、P等元素，是用鐵礦石經(jīng)高爐冶煉的產(chǎn)品。根據(jù)生鐵里碳存在形態(tài)的不同，又可分為煉鋼生鐵、鑄造生鐵和球墨鑄鐵等幾種。井蓋分為球墨鑄鐵井蓋、球墨井蓋、鑄鐵井蓋、高分子復(fù)合井蓋、防沉降井蓋、水泥井蓋、隱形井蓋、藝術(shù)井蓋、不銹鋼井蓋、五防井蓋、輕型井蓋、重型井蓋。所有的產(chǎn)品，規(guī)格型號可根據(jù)客戶要求定做（昆明多果商貿(mào)有限公司）。</span>昆明井蓋定制云南井蓋供應(yīng)商哪家好？</p><div
