球墨鑄鐵是通過(guò)球化和孕育處理取得球狀石墨，地提高了鑄鐵的機(jī)械性能，特別是提高了塑性與韌性，從而取得比碳鋼還高的強(qiáng)度。球墨鑄鐵是二十世紀(jì)五十年代發(fā)展起來(lái)的一種**度鑄鐵材料，其綜合性能接近于鋼，正是基于優(yōu)良的性能，它已成功地用于鑄造一些受力復(fù)雜，強(qiáng)度、韌性以及耐磨性要求較高的零件。所謂的“以鐵代鋼”，主要就是指球墨鑄鐵。在我國(guó)許多地區(qū)，球墨鑄鐵管在中、小口徑的給管與管之間的聯(lián)接，采用承插式或法蘭盤(pán)式接口方法；球墨鑄鐵，容許限制的轉(zhuǎn)角需要有優(yōu)良的抗震性和密封性。
