                                                                                                                                      常見的直縫鋼管用圖材質:Q195, Q215, Q235, Q345B, X42, X52, X60,下面說下鋼的型號,比如Q235,Q代表的是這種材質的屈服極限,后面的235,就是指這種材質的屈服值,在235MPa左右。并會隨著材質的厚度的增加而使其屈服值減小(板厚/直徑≤16mm,屈服強度為235MPa;16mm<板厚/直徑≤40mm,屈服強度為225MPa;40mm<板厚/直徑≤60mm,屈服強度為215MPa;60mm<板厚/直徑≤100mm,屈服強度為205MPa;100mm<板厚/直徑≤150mm,屈服強度為195MPa;150mm<板厚/直徑≤200mm,屈服強度為185MPa)。由于含碳適中,綜合性能較好,強度、塑性和焊接等性能得到較好配合,用途最廣泛。

                                                                                                                                      滄州市大唐管業有限公司始建于2007年,現已發展成為制造業500強,地處焊管產業基地河北滄州,是以生產高頻直縫焊接鋼管、托輥管、鐵塔和消防及其他工程用鋼管、Q345B及其他特殊材質鋼管、鍍鋅管、防腐熱鍍鋅及經營冷熱卷板、帶鋼、建筑材料與國際貿易為主的綜合性企業。
