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. 

北京方管市场价先降后回涨成交好涨价方管今天北京方管市场价先降后回涨。期螺夜盘由于系统原因，仅仅交易半小时，而这似乎有利于空头，最低砸到了3470。不过来到日盘，方管市场笑传永安开始自救，盘面也近乎一边倒的往上 拉，如此盘面被轻松拉到了3500点以上，3510也没有太大阻力，价格又收回近期点位；不过今日北京的表现似乎依然也没有过分的表现，主流大户早盘报… 方管企业需国内市场与国外市场一路硬拼方管方管企业缺乏市场营销意识，也没有自己的品牌，对国内市场不了解，营销人才、渠道资源、产品组合常常成为迈不过去的坎。不少谋求出口转内销的方管企业，由于没有渠道而苦不堪言。而长期做外贸的思维惯性，致使有的转型企业直接采用广告轰炸，低价竞争来抢市场渠道。显然这也非长久之计。实际上，国内外市场大相径庭，国内方管…
