不銹鋼無縫鋼管的機理介紹

今天山東無縫鋼管廠給大家介紹一下無縫不銹方管! Today, as an introduction shandong seamless steel pipe to seamless stainless square tube! 無縫不銹方管也稱不銹鋼無縫鋼管,是用鋼錠或?qū)嵭墓芘鹘?jīng)穿孔制成毛管,然后經(jīng)熱軋、冷軋或冷撥制成。無縫方管的規(guī)格用外徑*壁厚毫米數(shù)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不銹方管全稱SUS304不銹方管 304 stainless square tube full SUS304 stainless pipe SUS304不銹方管屬于美國牌號材質(zhì)的不銹方管,國內(nèi)牌號相當(dāng)于0Cr19Ni9不銹方管,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. 不銹鋼防銹的機理是合金元素形成致密氧化膜,隔絕氧接觸,阻止繼續(xù)氧化。所以不銹鋼并不是“不銹”。 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材料出現(xiàn)生銹現(xiàn)象,可能有以下幾個原因: 304 material appear rusty phenomenon, there may be several reasons: 使用環(huán)境中存在氯離子。氯離子廣泛存在,比如食鹽、汗跡、海水、海風(fēng)、土壤等等。不銹鋼在氯離子存在下的環(huán)境中,腐蝕很快,甚至超過普通的低碳鋼。 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. 所以對不銹鋼的使用環(huán)境有要求,而且需要經(jīng)常擦拭,除去灰塵,保持清潔干燥。 So the use of stainless steel environmental requirements, and often need to wipe, remove dirt, keep clean and dry. 316和317不銹鋼(317不銹鋼的性能見后)是含鉬不銹鋼種。317不銹鋼中的鉬含量略高明于316不銹鋼。由于鋼中鉬,該鋼種總的性能優(yōu)于310和304不銹鋼,高溫條件下,當(dāng)硫酸的濃度低于15%和高于85%時,316不銹鋼具有廣泛的用途。316不銹鋼還具有良好的而氯化物侵蝕的性能,所以通常用于海洋環(huán)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. 不銹方管隨著社會經(jīng)濟的發(fā)展,其應(yīng)用也得到了越來越廣泛的普及。必將在各個領(lǐng)域帶來全新的改觀。 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. 不銹方管的理論重量:W=(外徑壁厚)x壁厚x0。02491x長度 Don't rust square tube theory weight: W = wall thickness (diameter) x thickness x0.The length of the 02491 x 標(biāo)簽:[db:標(biāo)簽]
