style="text-indent:25px">冷拔異型鋼因形狀多變，有很多種型號，而按照鋼管截面形狀尺寸的不同又可分為等壁厚冷拔異型鋼（代號為D）、不等壁厚冷拔異型鋼（代號為BD）、變直徑冷拔異型鋼（代號為BJ）。異型無縫鋼管普遍用于各種結(jié)構(gòu)件、工具和機(jī)械零部件。和圓管相比，冷拔異型鋼一般都有較大的慣性矩和截面模數(shù)，有較大的抗彎抗扭能力，可以很大程度上減輕結(jié)構(gòu)重量，節(jié)約鋼材。新鄉(xiāng)市康弘機(jī)械有限公司生產(chǎn)銷售的冷拔異型鋼產(chǎn)品型號齊全，多樣，且價格適中，質(zhì)量好。</p><p
