短期西安方管市价稳中弱势运行价格下跌20-…方管西安方管市场价格下跌20-100元，当地包钢资源货少。今日管坯个别调整，山东地区各管厂出厂价格暂无变动，市场方面，西安方管市价主流价格下跌20-100元，现商家操作谨慎，对后市不大看好，补 库意愿不强，前期库存释放缓慢，临近五一，市场有让利走量的现象出现。市场观望情绪浓厚。预计短期西安方管市价稳中弱…

方管在使用状态下以铁素体组织为主的叫合金方管。含铬量在11%~30%，具有体心立方晶体结构。这类钢一般不含镍，有时还含有少量的Mo、Ti、Nb等到元素，这类钢具导热系数大，膨胀系数小、抗氧化性好、抗应力腐蚀优良等特点，多用于制造耐大气、水蒸气、水及氧化性酸腐蚀的零部件。这类合金方管存在塑性差、焊后塑性和耐蚀性明显降低等缺点，因而限制了它的应用。炉外精炼技术（AOD或VOD）的应用可使碳、氮等间隙元素大大降低，因此使这类钢获得广泛应用。

The square tube is called alloy square tube, which is mainly composed of ferrite in service state. The chromium content ranges from 11% to 30%. It has a body-centered cubic crystal structure. This kind of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This kind of steel tool has the characteristics of high thermal conductivity, small expansion coefficient, good oxidation resistance and excellent stress corrosion resistance. It is mostly used to manufacture parts resistant to atmospheric, steam, water and oxidative acid corrosion. This kind of alloy square pipe has some shortcomings, such as poor plasticity, obvious decrease of post-weld plasticity and corrosion resistance, which limits its application. The application of out-of-furnace refining technology (AOD or VOD) can greatly reduce the gap elements such as carbon and nitrogen, thus making this kind of steel widely used. 

南京镀锌方管价格将稳中趋弱运行为主维持进…方管南京镀锌方管市场价格下跌。今日期货上行，带钢价格小涨10元。本周方管厂家出厂价格一直维持平稳状态，今日个别探涨20元。据南京当地方管厂家反映，本周出货仍然平稳，相较于 11月份弱2-3成。库存方面保持谨慎操作，维持进出平衡。目前行情处于弱势平稳状态，下游需求有限，方管厂家普遍反映不做冬储，随需求灵活掌握。总体看… 乐从市场镀锌方管价格小幅上调厂家成交则略…方管今日乐从市场镀锌方管价格小幅上调，市场整体成交一般。据悉，但各方管厂家成交则略有不同。据悉，方管厂家报价和成交价的不同归根结底是出货量的不一，尤其是针对主要流通的柳方管资源。上月方管厂家的投放量明显增加，各代理商都有不同程度的增量，对于出货有压力的客户则以优惠成交为主，因此价格一直未像华东市场那样上涨…
