冷轧钢板就是经过冷轧生产的钢板，俗称冷板。　　冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。 　　一般来说，冷轧钢板分为三代产品：沸腾钢为第一代，铝镇静钢为第二代，无间隙原子刚（IF钢）为第三代。   您查询的关键词是：冷轧钢板  。如果打开速度慢，可以尝试快速版；如果想保存快照，可以添加到搜藏。 "冷轧钢板""2,冷轧钢板(YB459-64)""厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)",,"厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)""0.4","600x1200 700x1430 800x1500 1000x2000","3.56",,"2.5","6000x1200 7000x1430 800x1500 1000x2000","22.25""0.45",,"4.01",,"2.75",,"24.48""0.5",,"4.45",,"3.0",,"26.70""0.6",,"5.34",,"3.5",,"31.50""0.7",,"6.23",,"4.0",,"35.60""0.8",,"7.12",,"4.5",,"40.05""0.9",,"8.01",,"5.0",,"44.50""1.0",,"8.90",,"5.5",,"48.95""1.1",,"9.79",,"6.0",,"53.40""1.2",,"10.68",,"6.5",,"57.85""1.35",,"12.02",,"7.0",,"62.30""1.5",,"13.35",,"7.5",,"66.75""1.65",,"14.60",,"8.0",,"71.20""1.8",,"16.02",,"9.0",,"80.10""2.0",,"17.80",,"10.0",,"89.00""2.25",,"20.03""冷轧铜条""2,冷轧铜条(YB459-64)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)""0.20","200~400","500~800","1.78",,"2.50","200~500","500~2000","22.25""0.25",,,"2.23",,"2.75",,,"24.48""0.30",,,"2.67",,"3.00",,"1000~2000","26.70""0.35",,,"3.12",,"3.50",,,"31.15""0.40","200~500","500~2000","3.56",,"4.00",,,"35.60""0.45",,,"4.01",,"4.50",,,"40.05""0.50",,,"4.45",,"5.00",,,"44.50""0.60",,,"5.34",,"5.50",,,"48.95""0.70",,,"6.23",,"6.00",,,"53.40""0.80",,,"7.12",,"6.50",,,"57.85""0.90",,,"8.01",,"7.00",,,"62.30""1.00",,,"8.90",,"8.00",,,"71.20""1.20",,,"10.68",,"9.00",,,"80.10""1.30",,,"11.57",,"10.00",,,"89.00""1.40",,,"12.46",,"11.00",,,"97.90""1.50",,,"13.35",,"12.00",,,"106.8""1.60",,,"14.69",,"13.00",,,"115.7""1.80",,,"16.02",,"14.00",,,"124.6""2.00",,,"17.80",,"15.00",,,"133.5""注 铜板和条(热轧,冷轧)的制造牌号为T2,T3,T4和TU和TUP,其化学成分应符合YB145-71规定""特殊用冷轧黄铜条""3,特殊用冷轧黄铜条(YB555-65)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)""0.20","200~300","500~1000","1.76",,"1.6","200~500","500~2000","14.08""0.25",,,"2.20",,"1.8",,,"15.84""0.30","200~400",,"2.64",,"2.0",,,"17.60""0.35",,,"3.08",,"2.5",,,"22.00""0.40","200~500",,"3.52",,"2.75",,,"24.20""0.45",,,"3.96",,"3.0",,,"26.40""0.50",,"500~2000","4.40",,"3.5",,,"30.80""0.55",,,"4.84",,"4.0",,,"35.20""0.60",,,"5.28",,"4.5",,,"39.60""0.70",,,"6.16",,"5.0",,,"44.00""0.80",,,"7.04",,"5.5",,,"48.40""0.90",,,"7.92",,"6.0",,,"52.80""1.0",,,"8.8",,"6.5",,,"57.20""1.2",,,"10.56",,"7.0",,,"61.60""1.3",,,"11.44",,"8.0",,,"70.40""1.4",,,"12.32",,"9.0",,,"79.20""1.5",,,"13.20",,"10.0",,,"88.00""注 (1)标记举例:用H80制成的,厚度为0.8mm,宽度为300mm,长度为1000mm的1/2硬条标记为:"" 条H80-Y20.8x300x1000YB555-65.""

冷轧薄钢板，简称冷轧钢板、冷轧薄板、冷轧板、冷板等。它还包括不锈钢板、弹簧钢板、硬钢片、镀锌板、镀锡板、镀铝板等。冷轧薄钢带，简称冷轧钢带、冷轧带钢、钢带、带钢、薄钢带、冷轧卷等。还包括不锈钢带、镀锌钢带、镀锡钢带等。 冷轧钢板标准 冷轧薄钢板、钢带（以下简称冷轧薄板）主要用于零件的冲压加工，而冷轧薄板的力学性能十分重要，它直接关系到板材的冲压性能。冷轧薄板是以不同的热处理状态分级的，不同硬度的材料，用于不同的加工方法，国家标准GB/T 13237-1991《优质碳素结构钢冷轧薄钢板和钢带》将冷轧薄板大致分为三级，P级用于普通冲压，S级用于深度冲压，Z级用于最深度冲压。中国冶金标准YB/T 5059-1993《低碳钢冷轧钢带》将薄钢板按硬度分为五级，即：TR（特级）、R（软）、BR（半软）、DY（低硬）和Y（冷硬）。其实通过一定的冷轧变形程度和冷轧后热处理的恰当配合，可以在广泛的范围内满足用户关于材料力学性能方面的要求。冷轧薄板根据用户加工上的要求可以分成更多的级别。例如：日本工业标准JIS G3141-1996《冷轧碳素钢钢板和钢带》的分类除分为一般用（spcc）、冲压用(spcd)和深冲压用（spce）三类外，还细分为退火、标准调质、1/8硬、1/4硬、1/2硬、全硬等级别。 在冷轧薄板力学性能的检测方面，一些标准只规定了拉伸试验，另一些标准除拉伸试验外还规定了硬度试验。 中国标准GB/T 13237-1991就只规定了拉伸试验，技术要求冷轧钢板标准如表一所示：牌号 抗拉强度/MPa伸长率不小于拉延级别Z－S和PZSP08F275～365275～38034323008,08Al,10F275～390275～41032302810295～410295～43030392815F315～430315～45029282715335～450335～47027262520355～490335～50026252425——390～540——242330——440～590——222135——490～635——201940——510～650————1845——530～680————1650——540～715————14 日本标准JIS G3141-1996《冷轧碳素钢钢板和钢带》（该标准中包含了冷轧薄钢板和钢带）规定了拉伸试验，也规定了硬度试验，该标准的力学性能要求如下：表二：标准调质和退火的钢板、钢带的拉伸试验质牌号抗拉强度/MPa 不小于 伸长率/%不小于试样按以下公称厚度/mm>=0.250.250.400.601.01.6>=2.5SPCC SPCD SPCE(270) 270 270(32) 34 36(34) 36 3836 38 40　 37 39 41 　　 (38) 40 42 　39 41 435号试样轧制方向 表三：标准调质和退火的钢板、钢带的硬度值。调质区分符号 硬度最大HRBHV退火A57105标准调质S65115 注：厚度小于0.6mm的钢板和钢带，原则上不进行拉伸试验。 表四：1/8硬、1/4硬、1/2硬和全硬材料的拉伸试验值。调质区分 符号 抗拉强度/MPa伸长率/%最小试样1/8硬8294～410255号试样轧制方向1/4硬4370～490101/2硬2440～590——硬1>=550——     表五：1/8硬、1/4硬、1/2硬和全硬状态的硬度值。调质区分符号HRBHV1/8硬 1/4硬8450～7165～8095～130 115～1501/2硬 硬2174～89 ≥85135～185 ≥170注：HRB和HV，仅选用其中之一。英国标准BS 1449/1.9-1991《厚板、薄板和钢带第一部分：碳素钢和碳锰钢厚板、薄板和钢带具有成形性能的冷轧窄钢带技术条件》对冷轧板分级为CS1（铝镇静稳定化超深冲）、CS2（超深冲）、CS3（深冲）、CS4（折边）、CS15（商品级）。这项标准的力学性能要求如表六所示： 表六：钢材交货时的力学性能轧制状态和级别退火（A）或平整冷轧（SP）状态硬度HV1)2)最大屈服强度Re1)/MPa最小抗拉强度Rm1)/MPa最小伸长率A1)/%最小弯心直径1)（180°弯曲）原始标距LO50mm80mmCS1A9514027038（36）0aSP10514027036（34）0aCS2A9514027036（34）0a SP10014027036（34）0aCS3A100（140）（280）（34）（32）0aSP110（140）（280）（34）（32）0aCS4A105（140）（280）——0aSP115（140）（280）——0a 注：1）窄钢带交货应符合，或者硬度和弯曲试验，或者拉伸和弯曲试验，但硬度和拉伸试验不应同时进行。     2）对于SP（平整冷轧）状态，与镀层精整（PL）或镜面光洁度（MF），或以“无拉伸痕”交货的钢材组合，最大硬度可以提高5个HV或抗拉强度可以提高20MPa。     3）牌号CS2、CS3和CS4的硬度值仅适用于沸腾钢。 如上所述冷轧薄板的力学性能可以通过拉伸试验来检测，也可以通过硬度试验来检测。由于硬度试验设备简单、易于掌握，试验效率高，并且金属硬度与强度之间有一定的对应关系，所以硬度检测是确定材料力学性能的更方便的方法。冷轧薄板的硬度检测可以用于冷轧板生产过程的质量控制，更适于生产冲压产品的厂家对原材料进行力学性能的复检。 日本工业标准JIS G3141-1996规定的硬度试验是洛氏硬度HRB和维氏硬度HV。维氏硬度试验可用于冷轧薄板，但洛氏硬度HRB却不适用于测试薄板材料。因为当板材厚度小于2mm时，测试HRB硬度可能会因为发生“测砧效应”而使测量的硬度值失准。对于薄板材料，可以测试表面洛氏硬度HRN或HRT，然后换算成HRB或HV硬度。冷轧钢板标准生产了一种便携式表面洛氏硬度计，它非常适合测试薄板和钢带材料，它可以在生产现场、销售现场或材料仓库快速进行冷轧薄板材料的洛氏硬度检测，完成一次测量仅需要10秒钟时间，检测的板材厚度范围为0.05-50mm。这种仪器可以用在冷轧薄板带的生产线上，对产品的热处理效果进行在线的质量控制。这种仪器更适用于冲压产品的生产厂家。可以用它对购入的板材硬度进行复检，可以携带它去钢材市场选购材料，也可以利用它对自己厂生产的冲压产品进行硬度检测。 这种仪器如果配上一个支承座，还可以放到办公桌上使用。可以对成批的成品或半成品工件做逐件检测。它的测试精度与台式洛氏硬度计相同。 目前冷轧薄带材料正在向超薄方向发展，据报道，上海宝钢已扎制出厚度为0.08mm的冷轧薄板带材。采用本所生产的PHR-1S型表面洛氏硬度计，配一个金刚点砧座，就可测试薄至0.05mm冷轧薄板带材料的硬度。 这种应用完全可以取代维氏硬度计，使冷轧薄板材料的力学性能检测实现快速、简便、经济。

浅显地说，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因为其表面上富铬氧化膜（钝化膜）的构成。这种不锈性和耐蚀性是相对的。实验标明，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添加而进步，当铬含量到达必定的百分比时，钢的耐蚀性发作骤变，即从易生锈到不易生锈，从不耐蚀到耐腐蚀。不锈钢的分类办法许多。按室温下的安排结构分类，有马氏体型、奥氏体型、铁素体和双相不锈钢；按首要化学成分分类，基本上可分为铬不锈钢和铬镍不锈钢两大体系；按用处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；按功用特色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。因为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耐性等系列特色，所以在重工业、轻工业、生活用品职业以及建筑装修等职业中获取得广泛的运用。 奥氏体不锈钢在常温下具有奥氏体安排的不锈钢。钢中含Cr约18%、Ni 8%~10%、C约0.1%时，具有安稳的奥氏体安排。奥氏体铬镍不锈钢包含闻名的18Cr-8Ni钢和在此基础上添加Cr、Ni含量并参加Mo、Cu、Si、Nb、Ti等元素发展起来的高Cr-Ni系列钢。奥氏体不锈钢无磁性并且具有高耐性和塑性，但强度较低，不可能经过相变使之强化，仅能经过冷加工进行强化。如参加S，Ca，Se，Te等元素，则具有杰出的易切削性。此类钢除耐氧化性酸介质腐蚀外，假如含有Mo、Cu等元素还本领硫酸、磷酸以及、醋酸、尿素等的腐蚀。此类钢中的含碳量若低于0.03%或含Ti、Ni，就可显着进步其耐晶间腐蚀功能。高硅的奥氏体不锈钢浓硝酸肯有杰出的耐蚀性。因为奥氏体不锈钢具有全面的和杰出的归纳功能，在各行各业中取得了广泛的运用。　　铁素体不锈钢　　在运用状态下以铁素体安排为主的不锈钢。含铬量在11%~30%，具有体心立方晶体结构。这类钢一般不含镍，有时还含有少数的Mo、Ti、Nb比及元素，这类钢具导热系数大，膨胀系数小、抗氧化性好、抗应力腐蚀优秀等特色，多用于制作耐大气、水蒸气、水及氧化性酸腐蚀的零部件。这类钢存在塑性差、焊后塑性和耐蚀性显着下降一级缺陷，因而约束了它的运用。炉外精粹技能（AOD或VOD）的运用可使碳、氮等空隙元素大大下降，因而使这类钢取得广泛运用。　　奥氏体--铁素体双相不锈钢　　是奥氏体和铁素体安排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色，与铁素体比较，塑性、耐性更高，无室温脆性，耐晶间腐蚀功能和焊接功能均显着进步，一起还保持有铁素体不锈钢的475℃脆性以及导热系数高，具有超塑性等特色。与奥氏体不锈钢比较，强度高且耐晶间腐蚀和耐氯化物应力腐蚀有显着进步。双相不锈钢具有优秀的耐孔蚀功能，也是一种节镍不锈钢。　　马氏体不锈钢　　经过热处理能够调整其力学功能的不锈钢，浅显地说，是一类可硬化的不锈钢。典型牌号为Cr13型，如2Cr13 ,3Cr13 ,4Cr13等。粹火后硬度较高，不同回火温度具有不同强耐性组合，首要用于蒸汽轮机叶片、餐具、外科手术器械。依据化学成分的差异，马氏体不锈钢可分为马氏体铬钢和马氏体铬镍钢两类。依据安排和强化机理的不同，还可分为马氏体不锈钢、马氏体和半奥氏体（或半马氏体）沉积硬化不锈钢以及马氏体时效不锈钢等。

不锈钢与普通碳钢相比投资成本较高，使它一直不能用作普通结构件。不过目前评估结构件总体成本的因素越来越多，例如：耐腐蚀性，特别是在沿海地区，减少维修量和降低维修成本都会对整体寿命周期成本产生巨大的影响。　　核电工业就是一个典型的例子，在核电工业中，结构件需要有很长的使用寿命，因其不便于维修甚至不可 能进行维修。　　1．核工业　　以Sellafield核回收厂为例，该厂的接收和储藏池顶部（跨度为41．5米，长100米）的结构框架共用了350吨左右的321S12不锈钢。　　4米深的桁梁是用钢板压成角钢制作而成的，规格从200×200×1600mm到100×100×10mm。作为顶部檩子的矩形空心型材（300×200×8mm）是由圆形空心型材（直径324mm，厚度10mm）支撑的。　　2．砖墙支撑角钢　　在墙内的潜在腐蚀环境中，同样使用了数千吨不锈钢作为支撑砖墙的座角钢。　　这一点将在本文后面详细论述。　　3．露天体育场　　意大利新Bari体育场的维护是一大难题，而且是一项耗资巨大的工程，为此选用了不锈钢。　　涂有聚四氟乙烯的玻璃纤维漆布屋顶是由不锈钢构件和拉杆组成的框架支撑，把漆布绷紧。　　在使用直径为193．7mm，厚度为4～10mm的管材的同时，使用了20吨棒材和15吨板材。　　通过海上平台这种特殊应用实例，NiDI已经证明如果考虑整体寿命成本，即：首先是安装成本再加上日后的维护修理或更换部件的费用，采用不锈钢是一个节省开支的措施。不锈钢由于其美观和作为结构件的功能可以用作购物中心等场所的扶栏或作为表现建筑特征的玻璃支架。　　4．BOND街购物中心　　防火玻璃幕墙全部由不锈钢框架支撑。　　除活动接头外，从地面到各楼层一直到　　楼顶的竖框全部是一体的。竖框所用型钢为60X30X3mm的矩型空心型钢。　　在下面介绍的地铁系统中，由于减压系统的效应，设计中必须允许有空气压力差。　　预计空气的流速为5英里/小时，相当于0．25千牛顿／平方米的载荷。扶栏由竖框支撑，能承受的水平载荷为0．74千牛顿／平方米。　　安装后允许的挠度为25mm。通过变形或楼板间的垂直移动对框架进行补偿。　　5．BUSH LANE大厦　　该大厦充分表明了作为工程材料和结构用途的不锈钢的所有特点。由于位置的限制和由于下面是地铁网架桩深度的限制，构架位于建筑物外方。网架结构的结构件是用离心铸造生产的，具有12．5～30mm的不同厚度。节点为砂型铸造，为向伦敦市中心的一个建筑物提供必要时的防火，整个构架内充满了水。　　结构设计指南　　目前能够提供给设计人员的结构设计指南很有限，使现有的结构型材不能得到更广泛的应用。这种情况在最近几年发生了很大的变化。就材料本身而言，目前广泛出版的不锈钢标准共有57个标准钢种，按冶金结构可分为奥氏体、铁素体和马氏体，这么多的钢种会使设计中不常使用不锈钢的设计人员无从选择。他们最常提到的问题是"我该用哪个钢种？"这些材料的机械性能数据与碳钢的不同，使设计人员面临的问题更多。　　要帮助设计人员利用不锈钢，要采取哪些措施呢？过去的四年中，在日本、美国和欧洲出版了不锈钢结构设计指南。　　1．美国的研究成果　　为了对1974年出版的AISI冷成型结构设计手册进行修订，NiDI进行了为期四年的研究，其研究结果见1991年出版的美国国家标准协会（ANSI）和美国土木工程师学会（ASCE）标准ANSI／ASCE8-90。这本1974年出版的手册是许多年来结构设计人员唯一的一本关于不锈钢应用的资料。　　新的ANSI／ASCE标准是利用极限状态设计原则制定的。这一标准已经被过去几年中起草的绝大多数有关结构的业务法规所采用。　　不过许用应力的设计方法仍在使用。因为这两份文献都是现行的，采用哪种方法取决于设计人员。新的设计指南中的附件E只是简要地介绍了许用应力设计方法，详细内容见本项研究的（进展报告（3））。　　2．不锈钢钢种　　ANSI／ASCE标准中包括的材料如下；　　铁素体钢种：409、430和439　　奥氏体钢种：201、301、304和316　　经过退火的1／16、1／4和半硬材料都属于奥氏体钢，这些钢种冷加工时会产生加工硬化。　　NiDI和国际铬开发协会（现为国际铬开发协会）是该项目的赞助单位。　　3．英国的研究成果　　它们也是在英国所进行的研究的主要赞助单位，该研究结果将成为制定欧洲结构不锈钢标准的基础。　　该指南完全是依据极限状态原则编写的，它包括冷成型结构件和板材加工而成的结构件。研究过程中有些试验是在从未试验过的大型不锈钢型材上进行的。　　①钢种--英国研究成果　　尽管不锈钢的铁素体钢种包括在美国的ANSI／ASCE标准中，但未包括在英国设计手册中。　　英国的设计手册中只包括了三种奥氏体不锈钢钢种，即：　　奥氏体钢种：304L、316L和铁索体／奥氏体双相2205。　　选择少量钢种的原因很简单，因为目前可使用的碳结钢总共只有三种。使用L编号是因为这些低碳钢种能够焊接，不会出现与晶间腐蚀有关的问题。英国的手册中不包括加工硬化材料。这并不意味着不锈钢的其它钢种或加工硬化材料的使用不属于结构钢的应用范畴。　　双向不锈钢因两相兼有而强度高，其强度高于高强度碳钢，这种材料已成功地用于北海的海上石油平台。　　②BUSH LANE大厦　　该大厦是一个将双相不锈钢用作结构件的好例子。　　该大厦位于伦敦的CONNON街，地铁站上面纵横交错的地铁隧道限制了地桩的深度和位置。　　为此在建筑物的外边使用了结构框架，并利用网架结构将载荷传到支撑柱上。　　使用的离心铸管的直径分别为194mm、324mm和512mm，前两种铸管的壁厚9．5mm，最大的铸管管壁厚度为12．5～30mm。　　节点是砂铸的。　　采用的表面是经过玻璃球喷丸，表面加工相当于63CLA。材料的屈服强度为380N／mm2，抗拉强度650～780N／mm2，延伸率30％。该材料含碳0．08％，铬21％，镍5．5％，钼2％。　　NiDI和欧洲不锈钢协会（EUROINOX）已经出版了不锈钢结构设计手册。　　欧洲负责制定标准的机构计划出版一套不锈结构钢的业务规程，而且将编入EUROCODE3的1．4节中。　　NiDI已经将其研究结果提供给了编制EUROCODE的有关人员，1．4节就是按我们起草的内容编写的。　　设计规则　　为什么不锈钢不能沿用碳素结构钢的设计规则？　　碳钢的设计规则不能用于不锈钢是因为碳钢与不锈钢之间有着根本的区别：　　1．不锈钢没有屈服点，通常以ó0.2来表示该屈服应力被认为是当量值。　　2．应力／应变曲线形状不同，不锈钢的弹性极限大约是屈服应力的50％，就标准中所规定的最小值而论，该屈服应力值低于中碳钢的屈服应力值。　　3．冷加工时不锈钢产生加工硬化，例如，弯曲时具有各向异性，即：横向和纵向性能不同。　　可以利用由冷加工而增高的强度，不过如果与总面积相比弯曲面积较小而忽略不计这种增加时，强度增高可以在一定程度上提高安全系数。　　基本设计程序　　不锈钢的设计程序大体上是从现适用于结构工程设计的各个方面的原则派生出来的。　　但是由于通常使用的不锈钢是薄规格型钢，所以，它的设计过程比碳钢薄规格材料复杂得多。　　重要的是确定不锈钢的最终用途，因为在许多应用中不锈钢不仅作为结构件而且要起到美观的作用。　　为了防止构件受力部分出现局部弯曲和变形，关键的因素是材料的宽度和厚度之比的极限值。　　还有一点也很重要，值得一提，即：材料标准规定了ó0.2的最小值，对于建筑物所用的奥氏体不锈钢，该值大约是240N／mm2，但是，材料的特征强度一般要比该值高出15％，设计人员应将这一强度系数考虑在内。　　设计依据　　1．不锈钢和碳结钢之比较　　首先，看一下普通碳结钢与不锈钢之间的主要区别。　　2．应力／应变曲线图　　碳钢的应力／应变曲线的线性部分实际上是一条直达屈服点的直线，而不锈钢的线性区大约是ó0.2的50％。　　当应力级在非弹性区时，用于结构设计中的弯曲设计理论和虎克定律，即：应力与应变成比例，不真正适用于不锈钢。因此，在应力级较低的情况下，对不锈钢构件结构进行设计比较简单，但是在应力级较高的情况下，需要查阅变形和局部弯曲的标准。　　3．张力　　在现代结构法规中，拉伸应力加上载荷系数与毛断面的材料的屈服应力联系在一起，抗拉极限强度与屈服应力的比值用于校 验净截面。　　不锈钢的抗拉极限强度与屈服应力之比为2．4，而碳钢中该范围是1．6～2．1。　　拉伸构件需要对其强度进行两项检查：　　 ①毛断面的屈服应力　　 ②净有效断面的拉伸极限强度（最大 1．2）　　4．压力　　压力取决于屈服应力和模数，因为受压杆件的破坏通常是由于挠曲引起的，而挠曲本身又与刚度有关。因此，用减小E值来增大所能承受的力是很有必要的。因为这表明在细长比一定的条件下，不锈钢构件的纵向弯曲力低于相同的碳钢结构件。　　细长比较低时，两种材料一样。　　细长比较高时，应力低，强度类似，但细长比在80～120的中间值范围内，不锈钢的纵向弯曲力较低。　　5．弯曲　　在没有纵向弯曲情况下，弯曲应力一般与屈服应力有关。各种规则即使是含有弹性设计的规则，都认识到了形状系数的重要性。形状系数把梁的塑性力矩值增加到远远高于开始屈服时能力的值。　　但是，不锈钢应变硬化在开始屈服后立即开始，因此，外纤维增加而内纤维仍在弹性区内变形。所以，由于应变硬化，不锈钢能够具有较高的弯曲能力。　　不过在EUROCODE3第1．4节中没有提供塑性分析的内容。　　6．剪力和压力　　它们与刚度无关，而是直接关系到屈服应力和极限应力。应变硬化可以提高安全裕度。7.纵横向性能在英国的研究中，材料检验的结果普遍表明纵横性能差不超过7．5％。　　美国的结构分析和设计　　新版ANSI／ASCE标准利用许用载荷和力距替代了许用应力。　　因此，安全载荷的计算方法是在为所使用的构件和连接件计算得出的最大强度、纵向弯曲力或屈服力加上一个安全系数。大多数条款中还使用了无因次方程，从而可以方便地使用任何单位进行设计，同时还简化了载荷和抗力设计格式的转换。　　有关结构不锈钢的设计　　1．"冷成型结构件技术规格"，参见ANSI／ASCE8-90，可以向ASCE索取。　　2. EUROINOX（欧洲不锈钢）协会的"结构不锈钢设计手册"。　　不锈钢的耐高温性　　不锈钢作为结构件，例如，砖墙的支撑角钢，很可能会遇到出现火情时的高温。　　不锈钢的性能优于碳钢性能，NiDI在电缆桥架上进行的试验已经充分说明这一点，并在录像片"最有效的解决方法"中作了介绍。　　1.直接受热　　对电缆桥架进行直接受热试验是最能说明问题的。电缆桥架的承载能力相同。为了模拟典型的工作环境，试验时的加载量是它们可能承载的50％。　　3米长的桥架由18个煤气烧嘴加热，产生的温度高达1000℃ 以上。　　铝质桥架在26秒内完全毁坏。　　玻璃钢桥架没等烧嘴全部点燃就毁坏了。　　碳钢桥架经历了5分钟的试验，达到了炼油厂的要求，达到的最高温度是811℃ 。　　5分钟后的挠度为166mm。　　不锈钢桥架持续了45分钟，当时不幸的是罐内的气体被用完了。不过试验过程中，有14分钟温度在1000℃ 以上，有30分钟温度在900℃以上。　　在整个试验过程中，不锈钢不仅保持其结构的完整性，而且在试验结束时挠度只有80mm--不到碳钢的一半。　　这一性能是在厚度仅为2mm的试样上得出的。　　不锈钢不仅承受载荷能力的时间比碳钢长，而且不会通过导热使火情扩大。因为不锈钢的导热值较低。　　支撑砖砌体的角钢　　这种角钢广泛用于砖覆盖结构的承载件。不锈钢角钢连接在两层楼之间的混凝土或钢质框架上。这样可以快速、准确地安装面板。这种角钢的基本设计很简单，因为角钢被看作是一个支撑悬臂。为了计算有关的应力和挠度确定了三个简单的规则。　　有关这些设计规则的小册子可以向NiDI索取。按吨计算的话，支撑角钢每年在英国占有大约7000吨的市场。

冷轧钢板就是经过冷轧生产的钢板。冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，冷轧钢板的密度不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。冷轧钢板的密度：热轧钢板含碳量可比冷轧钢板略高些。在成份相持不大的情况下密度是一样的。但如果成份相差悬殊，如不锈钢不论冷轧、热轧密度都在7.9g/cm3左右。具体还要看成份，热轧只是延展性更好，钢材同样受到压力作用
