一(yi)、SA533GrB鍋(guo)爐容(rong)(rong)(rong)器(qi)板簡介：SA533GrB屬于(yu)鍋(guo)爐及(ji)壓(ya)力容(rong)(rong)(rong)器(qi)鋼板，執(zhi)行ASME SA387/SA387M標準。主要(yao)用(yong)于(yu)制造50立方米以上的球型貯(zhu)罐，9mm鍋(guo)爐容(rong)(rong)(rong)器(qi)鋼板市場價，也可用(yong)于(yu)制造單層(ceng)卷焊(han)容(rong)(rong)(rong)器(qi)、多(duo)層(ceng)熱套卷焊(han)容(rong)(rong)(rong)器(qi)、多(duo)層(ceng)包扎容(rong)(rong)(rong)器(qi)等二、三類容(rong)(rong)(rong)器(qi)及(ji)低溫壓(ya)力容(rong)(rong)(rong)器(qi)。

壓(ya)(ya)力容器(qi)板(ban)(ban)定(ding)(ding)(ding)義：用(yong)于制(zhi)(zhi)造蒸汽(qi)鍋爐、壓(ya)(ya)力容器(qi)及其他承壓(ya)(ya)容器(qi)結構(gou)件用(yong)的鋼板(ban)(ban)。這(zhe)種(zhong)鋼板(ban)(ban)由于承受(shou)一(yi)定(ding)(ding)(ding)的氣壓(ya)(ya)和水壓(ya)(ya)，9mm鍋爐容器(qi)鋼板(ban)(ban)訂購價，以(yi)及不(bu)同(tong)溫度的使用(yong)環境，如(ru)高、中、低溫等，因此對這(zhe)種(zhong)鋼板(ban)(ban)要求較為嚴格。除要求一(yi)定(ding)(ding)(ding)的強度、韌性外，9mm鍋爐容器(qi)鋼板(ban)(ban)制(zhi)(zhi)造商，還要求材質均(jun)勻，嚴格限制(zhi)(zhi)有害缺陷。

壓力(li)容器板(ban)種類：按(an)成分分類可分為碳(tan)素(su)鋼板(ban)、合金鋼板(ban)兩大類；按(an)強度分類可分為高、中(zhong)、低壓鋼板(ban)；按(an)使(shi)用(yong)環境分類可分為高、中(zhong)、低溫(wen)用(yong)鋼板(ban)及(ji)耐腐(fu)蝕鋼板(ban)。

       二 、 16Mo3歐標(biao)容(rong)器(qi)板化學成(cheng)分(wt%)：   三、 16Mo3歐標(biao)容(rong)器(qi)板機(ji)械性(xing)能(neng)：   焊(han)接時與其(qi)他(ta)材質不(bu)同，呼倫貝爾9mm鍋爐容(rong)器(qi)鋼板，要行預熱(re)，并且在焊(han)接完成(cheng)之后(hou)焊(han)縫(feng)(feng)還應保(bao)溫30分鐘左右。  16Mo3鋼板錳也是(shi)鋼材中(zhong)的重要合金(jin)元素(su)，也是(shi)重要的淬(cui)透性(xing)元素(su)，它對(dui)焊(han)縫(feng)(feng)金(jin)屬(shu)的韌性(xing)有很大影響。  16Mo3鋼板當Mn含量<0．05%時焊(han)縫(feng)(feng)金(jin)屬(shu)的韌性(xing)很高；
