Designation:A 268/A 268M –05aStandard Specification forSeamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service 1This standard is issued under the fixed designation A 268/A 268M;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon (e )indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope*1.1This specification 2covers a number of grades of nominal-wall-thickness,stainless steel tubing for general corrosion-resisting and high-temperature service.Most of these grades are commonly known as the “straight-chromium”types and are characterized by being ferromagnetic.Two of these grades,TP410and UNS S 41500(Table 1),are amenable to hardening by heat treatment,and the high-chromium,ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures.These features should be recognized in the use of these materials.Grade TP439is used primarily for hot-water tank service and does not require post-weld heat treatment to prevent attack of the heat affected zone.1.2An optional supplementary requirement is provided,and when desired,shall be so stated in the order.1.3The values stated in either inch-pound units or SI units are to be regarded separately as standard.Within the text,the SI units are shown in brackets.The values stated in each system are not exact equivalents;therefore,each system must be used independently of the bining values from the two systems may result in nonconformance with the specifi-cation.The inch-pound units shall apply unless the “M”designation of this specification is specified in the order.2.Referenced Documents 2.1ASTM Standards:3A 480/A 480M Specification for General Requirements for Flat-Rolled

Weld Zone of Welded Pipe and Tubing3.Terminology3.1Lot Definitions :3.1.1For flange and flaring requirements,the term lot applies to all tubes,prior to cutting,of the same nominal size and wall thickness that are produced from the same heat of steel.If final heat treatment is in a batch-type furnace,a lot shall include only those tubes of the same size and from the same heat that are heat treated in the same furnace charge.If the final heat treatment is in a continuous furnace,the number of tubes of the same size and from the same heat in a lot shall be determined from the size of the tubes as given in Table 2.3.1.2For tensile and hardness test requirements,the term lot applies to all tubes,prior to cutting,of the same nominal diameter and wall thickness that are produced from the same heat of steel.If final heat treatment is in a batch-type furnace,a lot shall include only those tubes of the same size and the same heat that are heat treated in the same furnace charge.If the final heat treatment is in a continuous furnace,a lot shall include all tubes of the same size and heat,heat treated in the same furnace at the same temperature,time at heat,and furnace speed.4.Ordering Information4.1It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specification.Such requirements may include,but are not limited to,the following:4.1.1Quantity (feet,metres,or number of lengths),4.1.2Name of material (seamless or welded tubes),4.1.3Grade (Table 1),4.1.4Size (outside diameter and nominal wall

For tubing smaller than1⁄2in.[12.7mm]in outside diameter,the elongation values given for strip specimens in Table2shall apply.Mechanical property requirements do not apply to tubing smaller than1⁄8in.[3.2mm]in outside diameter or with walls thinner than0.015in.[0.4mm].B For longitudinal strip tests a deduction of0.90%for TP446–1and S44735 and1.00%for all other grades shall be made from the basic minimum elongation foreach1⁄32in.[0.8mm]decrease in wall thickness below5⁄16in.[8mm].The following table gives the computed minimum values:A268/A268M–05a4巴巴客 免费下载标准12.Permissible Variations in Dimensions12.1Variations in outside diameter,wall thickness,and length from those specified shall not exceed the amounts prescribed in Table 6.12.2The permissible variations in outside diameter given in Table 6are not sufficient to provide for ovality in thin-walled tubes,as defined in the Table.In such tubes,the maximum and minimum diameters at any cross section shall deviate from the nominal diameter by no more than twice the permissible variation in outside diameter given in Table 6;however,the mean diameter at that cross section must still be within the given permissible variation.12.3When the specified wall is 2%or less of the specified outside diameter,the method of measurement is in accordance with the agreement between the purchaser and the manufac-turer (see Note 1).N OTE 1—Very thin wall tubing may not be stiff enough for the outside diameter to be accurately measured with a point contact test method,such as with the use of a micrometer or caliper.When very thin walls are specified,“go”–“no go”ring gages are commonly used to measure diameters of 11⁄2in.[38.1mm]or less.A0.002-in.[0.05-mm]additional tolerance is usually added on the “go”ring gage to allow clearance for sliding.On larger diameters,measurement is commonly performed with a pi tape.Other test methods such as optical test methods may also be considered.13.Surface Condition13.1All tubes shall be free of excessive mill scale,suitable for inspection.A slight amount of oxidation will not be considered as scale.Any special finish requirements shall be subject to agreement between the manufacturer and the pur-chaser.14.Mechanical Tests Required14.1Tension Tests —One tension test shall be made on a specimen for lots of not more than 50tubes.Tension tests shall be made on specimens from two tubes for lots of more than 50tubes.14.2Flaring Test (for Seamless Tubes)—One test shall be made on specimens from one end of one tube from each lot of finished tubes.The minimum expansion of the inside diameter shall be 10%.For tubes over 8in.[203.2mm]in outside diameter,or tubes with wall thickness 3⁄8in.[9.52mm]and over,the flattening test may be performed instead of the flaring test unless the flaring test is specified in the purchase order.14.3Flange Test (for Welded Tubes)—One test shall be made on specimens from one end of one tube from each lot of finished tubes.For tubes over 8in.[203.2mm]in outside diameter,or tubes with wall thickness 3⁄8in.[9.52mm]and over,the flattening test may be performed instead of the flange test unless the flange test is specified in the purchase order.14.4Hardness Test —Brinell or Rockwell hardness tests shall be made on specimens from two tubes from each lot.14.5When more than one heat is involved,the tension,flaring,flanging,and hardness test requirements shall apply to each heat.14.6Reverse Flattening Test —For welded tubes,one re-verse flattening test shall be made on a specimen from each 1500ft [450m]of finished tubing.15.Intergranular Corrosion Test15.1If intergranular corrosion testing is specified in the purchase order,the test shall be made in accordance withTABLE 4Minimum Elongation ValuesWall

马氏体不锈钢简介
马氏体不锈钢1、什么是不锈钢不锈钢（Sta in less Steel）是不锈耐酸钢的简称，耐空气、蒸汽、水等弱腐蚀介质或具有不锈性的钢种称为不锈钢；而将耐化学介质腐蚀（酸、碱、盐等化学浸蚀）的钢种称为耐酸钢。
由于两者在化学成分上的差异而使他们的耐蚀性不同，普通不锈钢一般不耐化学介质腐蚀，而耐酸钢则一般均具有不锈性。
2、分类不锈钢常按组织状态分为：马氏体钢、铁素体钢、奥氏体钢、奥氏体-铁素体（双相）不锈钢及沉淀硬化不锈钢等。
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1050〜1150C,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。

奥氏体马氏体铁素体的区别
奥氏体马氏体铁素体的区别The manuscript was revised on the evening of 2021奥氏体/马氏体/铁素体奥氏体（钢的组别：A1, A2, A3 A4, A5） (性能等级：50软，70冷加工，80高强度)马氏体(钢的组别：C1,C2,C3) (性能等级：50软，70、110淬火并回火，80淬火并回火) 铁素体(钢的组别：F1) (性能等级：45软，60冷加工)马氏体不锈钢属于铬不锈钢。
由于含碳量高，碳化铬多，钢的耐蚀性能下降，虽可通过热处理的方法改善，但防腐性不高。
马氏体不锈钢多用于制造力学性能要求较高，并有一定耐蚀性能要求的零件，如汽轮机叶片、喷嘴、阀座、量具、刃具等。
铁素体不锈钢也属于铬不锈钢。
含碳量小，抗大气、硝酸及盐水溶液的腐蚀能力强，有高温抗氧化性能好等特点。
主要用于制作化工设备中的容器、管道。
奥氏体不锈钢属于铬镍不锈钢。
具有很高的耐蚀性，优良的塑性，良好的焊接性及低温韧性，不具有磁性，易加工硬化。
主要用于在腐蚀介质中工作的零件、容器、管道、医疗器械以及抗磁环境中。
奥氏体奥氏体是碳溶解在γ－Fe中的间隙固溶体，常用符号A表示。
它仍保持γ－Fe的面心立方晶格。
其溶碳能力较大，在727℃时溶碳为ωc＝％,1148℃时可溶碳％。
奥氏体是在大于727℃高温下才能稳定存在的组织。
奥氏体塑性好，是绝大多数钢种在高温下进行压力加工时所要求的组织。
奥氏体是没有磁性的。
马氏体分级淬火是将奥氏体化工件先浸入温度稍高或稍低于钢的马氏体点的液态介质（盐浴或碱浴）中，保持适当的时间，待钢件的内、外层都达到介质温度后取出空冷，以获得马氏体组织的淬火工艺，也称分级淬火。
分级淬火由于在分级温度停留到工件内外温度一致后空冷，所以能有效地减少相变应力和热应力，减少淬火变形和开裂倾向。
分级淬火适用于对于变形要求高的合金钢和高合金钢工件，也可用于截面尺寸不大、形状复杂地碳素钢工件。
马氏体不锈钢通过热处理可以调整其力学性能的不锈钢，通俗地说，是一类可硬化的不锈钢。

马氏体Martensite，如前所述命名自AdolfMartens(1850-1914)。
这位被称作马登斯或马滕斯的先生是一位德国的冶金学家。
他早年作为一名工程师从事铁路桥梁的建设工作，并接触到了正在兴起
的材料检验方法。
于是他用自制的显微镜（！）观察铁的金相组织，并在1878年发表了《铁的显微镜研究》，阐述金属断口形态以及其抛光和酸浸后的金相组织。
（这个工作我们现在做的好像也蛮多的。
）他观察到生铁在冷却和结晶过程中的组织排列很有规则（大概其中就有马氏体），并预言显微镜研究必将成为最有用的分析方法之一（有远见）。
他还曾经担任了柏林皇家大学附属机械工艺研究所所长，也就是柏林皇家材料试验所（"StaatlicheMaterialprüfungsamt"）的前身，他在那里建立了第一流的金相试验室。
1895年国际材料试验学会成立，他担任了副主席一职。
直到现在，在德国依然有一个声望颇高的奖项以他的名字命名。

奥氏体、马氏体、铁素体、双相不锈钢的区别简介
不锈钢简介：不锈钢通俗地说，不锈钢就是不容易生锈的钢，实际上一部分不锈钢，既有不锈性，又有耐酸性（耐蚀性）。
不锈钢的不锈性和耐蚀性是由于其表面上富铬氧化膜（钝化膜）的形成。
这种不锈性和耐蚀性是相对的。
试验表明，钢在大气、水等弱介质中和硝酸等氧化性介质中，其耐蚀性随钢中铬含水量的增加而提高，当铬含量达到一定的百分比时，钢的耐蚀性发生突变，即从易生锈到不易生锈，从不耐蚀到耐腐蚀。
不锈钢的分类方法很多。
按室温下的组织结构分类，有马氏体型、奥氏体型、铁素体和双相不锈钢；按主要化学成分分类，基本上可分为铬不锈钢和铬镍不锈钢两大系统；按用途分则有耐硝酸不锈钢、耐硫酸不锈钢、耐海水不锈钢等等，按耐蚀类型分可分为耐点蚀不锈钢、耐应力腐蚀不锈钢、耐晶间腐蚀不锈钢等；按功能特点分类又可分为无磁不锈钢、易切削不锈钢、低温不锈钢、高强度不锈钢等等。
由于不锈钢材具有优异的耐蚀性、成型性、相容性以及在很宽温度范围内的强韧性等系列特点，所以在重工业、轻工业、生活用品行业以及建筑装饰等行业中获取得广泛的应用。
不锈钢牌号分组200 系列—铬-镍-锰奥氏体不锈钢300 系列—铬-镍奥氏体不锈钢型号301—延展性好，用于成型产品。
也可通过机械加工使其迅速硬化。
焊接性好。
抗磨性和疲劳强度优于304不锈钢。
型号302—耐腐蚀性同304，由于含碳相对要高因而强度更好。
型号303—通过添加少量的硫、磷使其较304更易切削加工。
型号304—通用型号；即18/8不锈钢。
GB牌号为0Cr18Ni9。
型号309—较之304有更好的耐温性。
型号316—继304之後，第二个得到最广泛应用的钢种，主要用于食品工业和外科手术器材，添加钼元素使其获得一种抗腐蚀的特殊结构。
由于较之304其具有更好的抗氯化物腐蚀能力因而也作“船用钢”来使用。
SS316则通常用于核燃料回收装置。
18/10级不锈钢通常也符合这个应用级别。
[1]型号321—除了因为添加了钛元素降低了材料焊缝锈蚀的风险之外其他性能类似304。

通过弯曲、硬度、化学成分试验和金相观察，验证了焊接参数和焊后热处理工艺对焊接接头性能的影响。
试验结论显示，采用埋弧焊堆焊304不锈钢层的ASTM A266钢可满足压缩机在耐腐蚀工况的防腐使用要求。
关键词：ASTM A266；防腐堆焊；埋弧焊中图分类号：TG142.71 文献标识码：A 文章编号：11-5004（2020）07-0258-2收稿日期：2020-04作者简介：张江楠，男，生于1985年，汉族，辽宁沈阳人，学士，中级工程师，研究方向：压缩机铆焊工艺。
近年来，随着离心压缩机市场的发展和产品种类逐渐增加，各种耐腐蚀环境的工况逐渐增多。
特别是随着海外市场产品的增多，因出口项目选材为ASME 材料，在遇到含硫化氢工况的机型时，与硫化氢接触过流部件如筒体、端盖、法兰、隔板等均需要考虑防腐。
设计方案一般是采用堆焊耐腐蚀层来实现防腐要求，堆焊层多选用奥氏体不锈钢。
因为奥氏体不锈钢中镍元素可有效防止硫化氢等腐蚀性介质引起的应力腐蚀开裂。
铬具有较强的抗氧化能力，在恶劣的腐蚀环境中具有良好的抗缝隙腐蚀和点蚀性能[1]。
因此，针对出口项目机壳所选用的ASME 材料的奥氏体堆焊工艺研究显得很有必要。
本项目针对日益增多的出口项目，通过几种不同的焊接方法的堆焊工艺研究，从而实现防腐堆焊要求的零部件，实现出口产品机壳的防腐要求。
1 试验材料与方法试验母材为ASTM A266 Grade2，满足ASTM A266标准，其化学成分及力学性能见表1，按其成分分类为低合金钢，碳当量为0.43，焊接性较好，但有裂纹倾向，焊接时要通过工艺手段加以控制。

77％,1148℃时可溶碳2。
11％。
奥氏体是在大于727℃高温下才能稳定存在的组织。
奥氏体塑性好,是绝大多数钢种在高温下进行压力加工时所要求的组织。
奥氏体是没有磁性的。
马氏体分级淬火是将奥氏体化工件先浸入温度稍高或稍低于钢的马氏体点的液态介质（盐浴或碱浴）中，保持适当的时间，待钢件的内、外层都达到介质温度后取出空冷，以获得马氏体组织的淬火工艺，也称分级淬火。
分级淬火由于在分级温度停留到工件内外温度一致后空冷,所以能有效地减少相变应力和热应力，减少淬火变形和开裂倾向。
分级淬火适用于对于变形要求高的合金钢和高合金钢工件，也可用于截面尺寸不大、形状复杂地碳素钢工件。
马氏体不锈钢通过热处理可以调整其力学性能的不锈钢，通俗地说,是一类可硬化的不锈钢。
典型牌号为Cr13型，如2Cr13 ,3Cr13 ，4Cr13等。
