鋼材價(jià)格步入下降通道，已弱勢(shì)下跌4個(gè)多月。截止2013年7月26日，鋼材價(jià)格指數(shù)降到，低于年初。鋼鐵工業(yè)協(xié)會(huì)重點(diǎn)統(tǒng)計(jì)的八個(gè)鋼材品種價(jià)格比年初均有不同程度的下降，平均跌幅。分品種來(lái)看。占我國(guó)鋼材產(chǎn)量比重較大的建筑用線材、螺紋鋼價(jià)格跌幅分別達(dá)，中厚板和熱軋卷板價(jià)格跌幅分別達(dá)。(三)鋼材出口增長(zhǎng)較快。國(guó)內(nèi)鋼材市場(chǎng)供需失衡刺激企業(yè)出口。1-6月，我國(guó)累計(jì)出口鋼材3069萬(wàn)噸，同比增長(zhǎng)，下降，進(jìn)口鋼坯和鋼錠32萬(wàn)噸，增長(zhǎng)50%。將坯材折合粗鋼，累計(jì)凈出口2506萬(wàn)噸，同比增長(zhǎng)，占我國(guó)粗鋼產(chǎn)量的。從出口價(jià)格看，1-6月出口棒線材均價(jià)，同比下降18%;板材，同比下降。(四)鋼廠及社會(huì)庫(kù)存高位運(yùn)行。市場(chǎng)供需矛盾向流通領(lǐng)域蔓延，國(guó)內(nèi)鋼材庫(kù)存延續(xù)上年末增長(zhǎng)態(tài)勢(shì)。3月15日達(dá)到歷史高的2252萬(wàn)噸，比上年高點(diǎn)增加351萬(wàn)噸，其中建筑鋼材庫(kù)存1432萬(wàn)噸，占庫(kù)存總量的。之后，隨著季節(jié)性消費(fèi)增加，庫(kù)存逐漸回落，7月26日降至1540萬(wàn)噸。市場(chǎng)供大于求也推高鋼廠庫(kù)存，3月中旬重點(diǎn)企業(yè)鋼材庫(kù)存創(chuàng)歷史記錄，達(dá)到1451萬(wàn)噸，同比增長(zhǎng)，6月下旬降至1268萬(wàn)噸，仍比年初增長(zhǎng)，比2012年同期增長(zhǎng)。(五)鋼廠盈利水平逐月下滑。2013年上半年，冶金行業(yè)實(shí)現(xiàn)利潤(rùn)，同比增長(zhǎng)。西藏309s不銹鋼無(wú)縫管廠家現(xiàn)貨無(wú)縫鋼管采用的是圓管坯作為原料進(jìn)行穿孔，通過(guò)冷軋、冷拔或者熱擠壓的生產(chǎn)工藝制作而成，管上沒(méi)有焊接點(diǎn)。</p><div
