今天山东无缝钢管厂给大家介绍一下无缝不锈方管！ Today, as an introduction shandong seamless steel pipe to seamless stainless square tube! 无缝不锈方管也称不锈钢无缝钢管，是用钢锭或实心管坯经穿孔制成毛管，然后经热轧、冷轧或冷拨制成。无缝方管的规格用外径*壁厚毫米数表示。 Seamless stainless pipe also called stainless steel seamless steel tube, is made from solid tube ingot or the perforation capillary, then through hot rolling and cold rolling or cold dial.* wall thickness of the specifications of the seamless steel square tube with diameter mm number representation. 304不锈方管全称SUS304不锈方管 304 stainless square tube full SUS304 stainless pipe SUS304不锈方管属于美国牌号材质的不锈方管，国内牌号相当于0Cr19Ni9不锈方管，通常用 0Cr18Ni9替代。 SUS304 stainless square tube belongs to the American brand material of stainless tube, domestic brand is equal to 0 cr19ni9 stainless tube, usually use 0 cr18ni9 alternative. 不锈钢防锈的机理是合金元素形成致密氧化膜，隔绝氧接触，阻止继续氧化。所以不锈钢并不是“不锈”。 Stainless steel rust is the mechanism of alloy elements to form dense oxide film, isolated from oxygen contact, prevent to oxidation.Stainless steel is not so "stainless". 304材料出现生锈现象，可能有以下几个原因： 304 material appear rusty phenomenon, there may be several reasons: 使用环境中存在氯离子。氯离子广泛存在，比如食盐、汗迹、海水、海风、土壤等等。不锈钢在氯离子存在下的环境中，腐蚀很快，甚至超过普通的低碳钢。 Using chloride ion exist in the environment.Chloride ion is widespread, such as salt, HanJi, sea, sea wind, soil and so on.Stainless steel in the presence of chloride ions in the environment, corrosion soon, even more than ordinary low carbon steel. 所以对不锈钢的使用环境有要求，而且需要经常擦拭，除去灰尘，保持清洁干燥。 So the use of stainless steel environmental requirements, and often need to wipe, remove dirt, keep clean and dry. 316和317不锈钢（317不锈钢的性能见后）是含钼不锈钢种。317不锈钢中的钼含量略高明于316不锈钢。由于钢中钼，该钢种总的性能优于310和304不锈钢，高温条件下，当硫酸的浓度低于15%和高于85%时，316不锈钢具有广泛的用途。316不锈钢还具有良好的而氯化物侵蚀的性能，所以通常用于海洋环境。 The performance of the 316 and 317 stainless steel (317 stainless steel see after) is molybdenum stainless steel.Molybdenum content of 317 stainless steel was a little bit clever than 316 stainless steel.Because of molybdenum in steel, the steel grade overall performance is better than that of 310 and 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less than 15% and higher than 85%, the 316 stainless steel has a wide range of USES.316 stainless steel also has good performance of chloride erosion, so often used in Marine environment. 不锈方管随着社会经济的发展，其应用也得到了越来越广泛的普及。必将在各个领域带来全新的改观。 Stainless tube with the development of social economy, the popularization of its application also got more and more widely.Will bring new change in all fields. 不锈方管的理论重量：W=(外径壁厚)x壁厚x0。02491x长度 Don't rust square tube theory weight: W = wall thickness (diameter) x thickness x0.The length of the 02491 x 标签：[db:标签]
