class="khcont">無縫鋼管在什么狀態(tài)下被稱為答在使用狀態(tài)下以鐵素體組織為主的合金方管。含鉻量在11%~30%，具有體心立方晶體結(jié)構(gòu)。這類鋼一般不含鎳，有時(shí)還含有少量的Mo、Ti、Nb等到元素，這類鋼具導(dǎo)熱系數(shù)大，膨脹系數(shù)小、抗氧化性好、抗應(yīng)力腐蝕優(yōu)良等特點(diǎn)，多用于制造耐大氣、水蒸氣、水及氧化性酸腐蝕的零部件。這類合金方管存在塑性差、焊后塑性和耐蝕性明顯降低等缺點(diǎn)，因而限制了它的應(yīng)用。爐外精煉技術(shù)（AOD或VOD）的應(yīng)用可使碳、氮等間隙元素大大降低，因此使這類鋼獲得廣泛應(yīng)用。是奧氏體和鐵素體組織各約占一半的合金方管。在含C較低的情況下，Cr含量在18%~28%，Ni含量在3%~10%。有些鋼還含有Mo、Cu、Si、Nb、Ti，N等合金元素。該類鋼兼有奧氏體和鐵素體合金方管的特點(diǎn)，與鐵素體相比，塑性、韌性更高，無室溫脆性，耐晶間腐蝕性能和焊接性能均顯著提高，同時(shí)還保持有鐵素體合金方管的475℃脆性以及導(dǎo)熱系數(shù)高，具有超塑性等特點(diǎn)。與奧氏體合金方管相比，強(qiáng)度高且耐晶間腐蝕和耐氯化物應(yīng)力腐蝕有明顯提高。</div><p><img

class="khcont">據(jù)悉，當(dāng)前無縫鋼管庫存高壓進(jìn)一步趨緩，價(jià)格無疑得到支撐，不過，以長材為代表的高價(jià)背后高利潤仍使得鋼廠供應(yīng)偏強(qiáng)，多空操作仍需加大關(guān)注。短期來看，國內(nèi)無縫方矩管價(jià)格或延續(xù)穩(wěn)中反復(fù)震蕩為主。市場商家心態(tài)開始出現(xiàn)轉(zhuǎn)變，報(bào)價(jià)方面也開始不斷松動。無縫鋼管另一方面，目前生產(chǎn)企業(yè)對于短期市場的走向并未給出明確的引導(dǎo)，出廠價(jià)格以持穩(wěn)或挺價(jià)為主，因此多數(shù)區(qū)域商家報(bào)價(jià)也并未急于下調(diào)，操作上仍以穩(wěn)價(jià)出貨居多。按需購買無縫方矩管原材料，市場整體操作意愿薄弱，觀望情緒濃厚，當(dāng)前原材料利潤尚存，部分成品鋼廠開始外賣方矩管，使市場流通資源更多，鋼廠挺價(jià)意愿較強(qiáng)，經(jīng)銷商無奈挺價(jià)賣貨，但成交并不理想，市場供需矛盾凸出，在市商家基本持謹(jǐn)慎觀望心態(tài)，故預(yù)計(jì)下周無縫方矩管價(jià)格窄幅下調(diào)。根據(jù)前段時(shí)期的調(diào)查顯示，163家無縫方矩管廠高爐產(chǎn)能利用率86%較上周降0.46%，剔除淘汰產(chǎn)能的利用率為846%較去年同期持平，鋼廠盈利率844%持平。紅六月鋼廠利潤高企，晝夜全力生產(chǎn)，導(dǎo)致部分鋼廠高爐、轉(zhuǎn)爐、電爐、軋線相關(guān)等一系列設(shè)備存在超負(fù)荷硬傷，7月進(jìn)入集修階段。檢修高爐容積合計(jì)18890m3;影響產(chǎn)量約49萬噸，產(chǎn)能利用率821%，較上周上升49%。剔除2016年去產(chǎn)能淘汰高爐后產(chǎn)能利用率約在995%，較上周上升48%。</div><p><img
