不锈钢概述
播报编辑奥氏体不锈钢相当于国产0Cr18Ni10Ti美国牌号为：321、S32100、TP321特性321不锈钢其中的Ti作为稳定化元素存在,但它同时是热强钢种,在高温方面比316L要好的多.321不锈钢在不同浓度、不同温度的有机酸和无机酸中,尤其是在氧化性介质中具有良好的耐磨蚀性能,用于制造耐磨酸容器和耐磨设备的衬里、输送管道。321不锈钢是Ni-Cr-Ti型奥氏体不锈钢，其性能与304非常相似，但是由于加入了金属钛，使其具有了更好的耐晶界腐蚀性及高温强度。由于添加金属钛，使其有效的控制了碳化铬的形成。321不锈钢图片321不锈钢具有的优异的高温应力破断(Stress Rupture)性能及高温抗蠕变性能(Creep Resistance)应力机械性能都优于304不锈钢。适宜做高温下使用的焊接构件。应用应用于抗晶界腐蚀性要求高的化学、煤炭、石油产业的野外露天机器，建材耐热零件及热处理有困难的零件，如：1 . 石油废气燃烧管道2 . 发动机排气管3 . 锅炉外壳，热交换器，加热炉部件4 . 柴油机用消音部件5 . 锅炉压力容器6 . 化学品运输车7 . 伸缩接头8 . 燃炉管道及烘干机用螺旋焊管9.航空器公差321不锈钢尺寸及允许偏差偏差等级标准化外径允许偏差D1±1.5%，最小±0.75 mmD2±1.0%。最小±0.50 mmD3±0.75%．最小±0.30 mmD4±0.50%。最小±0.10 mm不锈钢管重量公式:[(外径-壁厚)*壁厚]*0.02491=kg/米(每米的重量)

不锈钢知识
播报编辑321不锈钢不锈钢（Stainless Steel）指耐空气、蒸汽、水等弱腐蚀介质和酸、碱、盐等化学浸蚀性介质腐蚀的钢， 　又称不锈耐酸钢。实际应用中，常将耐弱腐蚀介质腐蚀的钢称为不锈钢，而将耐化学介质腐蚀的钢称为耐酸钢。由于两者在化学成分上的差异，前者不一定耐化学介质腐蚀，而后者则一般均具有不锈性。不锈钢的耐蚀性取决于钢中所含的合金元素。种类不锈钢常按组织状态分为：马氏体钢、铁素体钢、奥氏体钢等。另外，可按成分分为：铬不锈钢、铬镍不锈钢和铬锰氮不锈钢等。　 　1、铁素体不锈钢：含铬12%～30%。其耐蚀性、韧性和可焊性随含铬量的增加而提高，耐氯化物应力腐蚀性能优于其他种类不锈钢。 　属于这一类的有Crl7、Cr17Mo2Ti、Cr25，Cr25Mo3Ti、Cr28等。铁素体不锈钢因为含铬量高，耐腐蚀性能与抗氧化性能均比较好，但机械性能与工艺性能较差，多用于受力不大的耐酸结构及作抗氧化钢使用。这类钢能抵抗大气、硝酸及盐水溶液的腐蚀，并具有高温抗氧化性能好、热膨胀系数小等特点，用于硝酸及食品工厂设备，也可制作在高温下工作的零件，如燃气轮机零件等。 　2、奥氏体不锈钢：含铬大于18%，还含有 8%左右的镍及少量钼、钛、氮等元素。综合性能好，可耐多种介质腐蚀。奥氏体不锈钢的常用牌号有1Cr18Ni9、0Cr19Ni9等。0Cr19Ni9钢的wC＜0.08%，钢号中标记为“0”。这类钢中含有大量的Ni和Cr，使钢在室温下呈奥氏体状态。这类钢具有良好的塑性、韧性、焊接性和耐蚀性能，在氧化性和还原性介质中耐蚀性均较好，用来制作耐酸设备，如耐蚀容器及设备衬里、输送管道、耐硝酸的设备零件等。奥氏体不锈钢一般采用固溶处理，即将钢加热至1050～1150℃，然后水冷，以获得单相奥氏体组织。 　3、奥氏体 - 铁素体双相不锈钢：兼有奥氏体和铁素体不锈钢的优点，并具有超塑性。 　奥氏体和铁素体组织各约占一半的不锈钢。在含C较低的情况下，Cr含量在18%~28%，Ni含量在3%~10%。有些钢还含有Mo、Cu、Si、Nb、Ti，N等合金元素。该类钢兼有奥氏体和铁素体不锈钢的特点，与铁素体相比，塑性、韧性更高，无室温脆性，耐晶间腐蚀性能和焊接性能均显著提高，同时还保持有铁素体不锈钢的475℃脆性以及导热系数高，具有超塑性等特点。与奥氏体不锈钢相比，强度高且耐晶间腐蚀和耐氯化物应力腐蚀有明显提高。双相不锈钢具有优良的耐孔蚀性能，也是一种节镍不锈钢。 　4、马氏体不锈钢：强度高，但塑性和可焊性较差。 　马氏体不锈钢的常用牌号有1Cr13、3Cr13等，因含碳较高，故具有较高的强度、硬度和耐磨性，但耐蚀性稍差，用于力学性能要求较高、耐蚀性能要求一般的一些零件上，如弹簧、汽轮机叶片、水压机阀等。这类钢是在淬火、回火处理后使用的。不锈钢作用不锈钢不会产生腐蚀、点蚀、锈蚀或磨损。不锈钢还是建筑用金属材料中强度最高的材料之一。由于不锈钢具有良好的耐腐蚀性，所以它能使结构部件永久地保持工程设计的完整性。含铬不锈钢还集机械强度和高延伸性于一身，易于部件的加工制造，可满足建筑师和结构设计人员的需要 　。典型用途大多数的使用要求是长期保持建筑物的原有外貌。在确定要选用的不锈钢类型时，主要考虑的是所要求的审美标准、所在地大气的腐蚀性以及要采用的清理制度。 　然而，其它应用越来越多的只是寻求结构的完整性或不透水性。例如，工业建筑的屋顶和侧墙。在这些应用中，物主的建造成本可能比审美更为重要，表面不很干净也可以。 　在干燥的室内环境中使用304不锈钢效果相当好。但是，在乡村和城市要想在户外保持其外观，就需经常进行清洗。在污染严重的工业区和沿海地区，表面会非常脏，甚至产生锈蚀。但要获得户外环境中的审美效果，就需采用含镍不锈钢。所以，304不锈钢广泛用于幕墙、侧墙、屋顶及其它建筑用途，但在侵蚀性严重的工业或海洋大气中，最好采用316不锈钢。 　不锈钢拉门 　人们已充分认识到了在结构应用中使用不锈钢的优越性。有几种设计准则中包括了304和316不锈钢。因为"双相"不锈钢2205已把良好的耐大气腐蚀性能和高抗拉强度及弹限强度融为一体，所以，欧洲准则中也包括了这种钢。 　产品形状 　实际上，不锈钢是以全标准的金属形状和尺寸生产制造的，而且还有许多特殊形状。最常用的产品是用薄板和带钢制成的，也用中厚板生产特殊产品，例如，生产热轧结构型钢和挤压结构型钢。而且还有圆型、椭圆型、方型、矩型和六角型焊管或无缝钢管及其它形式的产品，包括型材、棒材、线材和铸件。表面状态正如后面将谈到的，为了满足建筑师们美学的要求，已开发出了多种不同的商用表面加工。例如，表面可以是高反射的或者无光泽的；可以是光面的、抛光的或压花的；可以是着色的、彩色的、电镀的或者在不锈钢表面蚀刻有图案，也可进行拉丝等，以满足设计人员对外观的各种要求。 　保持表面状态是容易的。只需偶尔进行冲洗就能去除灰尘。由于耐腐蚀性良好，也可以容易地去除表面的涂写污染或类似的其它表面污染。未来展望由于不锈钢已具备建筑材料所要求的许多理想性能，它在金属中可以说是独一无二的，而其发展仍在继续。为使不锈钢在传统的应用中性能更好，一直在改进现有的类型，而且，为了满足高级建筑应用的严格要求，正在开发新的不锈钢。由于生产效率不断提高，质量不断改进，不锈钢已成为建筑师们选择的最具有成本效益的材料之一。 　不锈钢集性能、外观和使用特性于一身，所以不锈钢仍将是世界上最佳的建筑材料之一。新手上路成长任务编辑入门编辑规则本人编辑我有疑问内容质疑在线客服官方贴吧意见反馈投诉建议举报不良信息未通过词条申诉投诉侵权信息封禁查询与解封©2025 Baidu 使用百度前必读 | 百科协议 | 隐私政策 | 百度百科合作平台 | 京ICP证030173号 京公网安备11000002000001号window.PAGE_DATA=
