  球墨鑄鐵管的主要成分有碳、硅、錳、硫、磷和鎂等。在鐵素體和珠光體基體上分布有一定數(shù)量的球狀石墨，根據(jù)公稱口徑及對延伸率的要求不同，基體組織中的鐵素體和珠光體的比例有所不同，小口徑的珠光體比例一般不大于20%，大口徑的一般控制在25%左右。最小抗拉強度：420Mpa，最小屈服強度300Mpa，最小延伸率7%。????????球墨鑄鐵管執(zhí)行標準GBT13295-2008??ISO25312008????????執(zhí)行國家GBT13295-91標準ISO2531-K9級。????????下面是江陰魯寶管業(yè)有限公司的球墨鑄鐵管規(guī)格及報價：????????品名規(guī)格材質(zhì)重量根(KG單價備注????????DN100球墨鑄鐵9552006米??????????????????DN150球墨鑄鐵14441006米????????????????DN200球墨鑄鐵19440006米????????DN250球墨鑄鐵25506米??????????????????????DN300球墨鑄鐵32339506米????????????????DN350球墨鑄鐵40306米????????DN400球墨鑄鐵48239506米????????????????DN450球墨鑄鐵57740506米????????????????DN500球墨鑄鐵66940506米????????DN600球墨鑄鐵88241506米????????????????DN700球墨鑄鐵112342506米??????????????DN800球墨鑄鐵139443006米????????DN900球墨鑄鐵169006米????????????????????DN1000球墨鑄鐵201706米??????????????????DN1200球墨鑄鐵275806米
