無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)有很(hen)(hen)多種(zhong)規(gui)格和(he)(he)類型,Q345B無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)就是(shi)(shi)(shi)比較常見的(de)(de)一(yi)種(zhong),不過很(hen)(hen)多人對于還并不了(le)解(jie)這(zhe)(zhe)種(zhong)鋼(gang)(gang)管(guan)(guan)(guan),下面,無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)廠家就給大家講解(jie)了(le)什(shen)么是(shi)(shi)(shi)Q345B無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)以及其優點(dian).　　什(shen)么是(shi)(shi)(shi)Q345B無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)?　　Q345B無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)也就是(shi)(shi)(shi)16Mn鋼(gang)(gang)管(guan)(guan)(guan),16Mn為(wei)鋼(gang)(gang)材(cai)中的(de)(de)一(yi)種(zhong)材(cai)質,是(shi)(shi)(shi)過去(qu)的(de)(de)一(yi)種(zhong)叫法,現(xian)如今稱之為(wei)Q345B,Q代表的(de)(de)是(shi)(shi)(shi)這(zhe)(zhe)種(zhong)材(cai)質的(de)(de)屈(qu)服而345就是(shi)(shi)(shi)指這(zhe)(zhe)種(zhong)材(cai)質的(de)(de)屈(qu)服值.　　Q345B無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)的(de)(de)優點(dian)有哪(na)些(xie)?　　無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)廠家指出,Q345B無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)具有承受高壓無(wu)(wu)(wu)泄漏、高精度、高光潔度、冷彎不變形(xing)、擴口(kou)、壓扁無(wu)(wu)(wu)裂縫(feng)(feng)等優點(dian),可作(zuo)使用(yong)溫度為(wei)580℃的(de)(de)鍋(guo)爐過熱器管(guan)(guan)(guan),也可用(yong)于壓力容器等.　　Q345B無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)屬(shu)于無(wu)(wu)(wu)鉻多元(yuan)素(su)貝(bei)氏體型熱強(qiang)鋼(gang)(gang),有著(zhu)很(hen)(hen)高的(de)(de)熱強(qiang)性(xing)、抗氧化(hua)性(xing)和(he)(he)組(zu)織穩定性(xing),所以適用(yong)范圍很(hen)(hen)廣.
