它的厚度范围一般在3/16英寸到8英寸之间，常见的宽度有36英寸、48英寸和60英寸等。

A572钢板是一种高强度低合金结构钢板，具有较高的强度和良好的耐蚀性能。

它的厚度范围一般在1/4英寸到4英寸之间，常见的宽度有48英寸、60英寸和72英寸等。

A588钢板是一种耐候钢板，具有良好的耐候性和抗腐蚀性能。

它的厚度范围一般在3/16英寸到4英寸之间，常见的宽度有48英寸和60英寸等。

A514钢板是一种高强度合金钢板，主要用于制造重型设备和机械零件。

它的厚度范围一般在1/4英寸到8英寸之间，常见的宽度有48英寸和96英寸等。

A516钢板是一种用于制造压力容器的碳素钢板，具有良好的耐高温性能和耐腐蚀性能。

它的厚度范围一般在1/4英寸到4英寸之间，常见的宽度有48英寸和96英寸等。

这些钢板规格在建筑、制造、船舶、桥梁等领域都有广泛的应用。

了解和掌握这些常用钢板规格，对于正确选择和使用钢板材料具有重要意义。

Introduction - AISI ASTM ASME and UNSMost ASTM and ASME standards list the steel grades by their UNS (Unified Numbering system) numbers but also make reference, where appropriate to the more general AISI (American Iron and Steel Institute) grade designations. These grade numbering systems are widely used in the USA, where they originated and are recognized by most stainless steel specifies and users. The American Iron and Steel Institute (AISI) developed designations such as 304, 430 etc and published compositions for these in their 'Steel Products Manual' (1974).These are NOT specifications, but steel grade composition ranges only.These grades were used by the American Society Testing and Materials (ASTM) to identify grades in a wide range of standards they published for stainless products, such as sheets and plates (ASTM A240), bars (ASTM A276) and tubes (ASTM A269). The compositions of the AISI grades were made more specific with the introduction of the 'Unified Numbering System', jointly established by ASTM and SAE (Society of Automotive Engineers).This five digit number, preceded by the letter 'S' for most stainless steels, identified the specific variant of the gradee.g. 304 being UNS S30400, 304L being UNS S30403American Society of Mechanical Engineers (ASME) publish design codes and standards for pressure applications. ASME standards are generally based on the appropriate ASTM standards, but the standard numbers are preceded with the letters 'SA', rather than just the 'A' of the ASTM standards.Where UNS grade numbers are used, these are universal, regardless of the product type or the standard in which they appear.The AISI designations have been adopted in Japan. The AISI number is preceded with the letters SUS e.g. SUS 304. The Japanese have developed variants on some grades for certain product forms e.g. SUS 304J1 for sheet products.The composition ranges should always be checked in the appropriate standard.Composition tablesThe tables in this article use the UNS number as their key, but also show the related AISI and SAE numbers. Where appropriate, common names for the steels are also shown.There are some differences in the composition ranges for some grades between flat and long products. This is due to the harmonisation process which is aimed to bring US and European compositions into line. This process is more advanced for flat products than for long.Consequently, there will be small differences until this process is complete. Where there is a different composition depending on product form, both compositions are shown.As an alternative to scanning down the list try the 'find' facility on your keyboard, using the 'Ctrl' and 'F' keys together.

SA542TypeDCL4a美标容器板成分性能及应用范围

SA542TypeDCL4a1、SA542TypeDCL4a 车冈板简介SA542TypeDCL4a是国际上新近发展起来的高温高压反应器材料。

在此之前，SA387Gr22CL2 钢板由于其良好的高温力学性能、抗高温氧化性能、抗腐蚀性能、良好的韧性和可焊性在世界上使用广泛。

但在新的使用技术和条件中SA387Gr22CL2已经无法满足生产需要，SA542TypeDCL4a的出现尤为重要。

SA542TypeDCL4a是在在强度、抗氢性能、抗回火脆化能力、抗氢致剥离能力等方面都较SA387Gr22CL2钢板有较大提高。

2、SA542TypeDCL4a钢板执行标准：执行美标ASME SA-542/SA-542M标准(与ASTM标准A542/A542M-09 完全等同)。

3、SA542TypeDCL4a钢板交货状态：A、所有钢板都须进行热处理，此时可将钢板加热到适当的奥氏体化温度，保温足够时间以使整个厚度上温度均匀，并用适宜的液体介质以喷射或浸入法进行淬火。

D型材料的最低奥氏体化温度应为900C。

E型材料的最低奥氏体化温度应为1010℃oB、淬火后，将钢板回火以获得所规定的拉伸性能要求。

回火时，钢板加热至适当的温度并保温一段时间，回火温度应不低于675℃。

C、厚度大于100nm i的钢板在按A规定处理前，对D型钢板在900-1010℃的温度范围内某以温度下进行预先正火处理或水淬。

D、未经上述热处理的钢板，应以经受消除应力处理状态或以退火状态供货、钢板的消除应力处理温度应不低于565℃。

6、SA542TypeDCL4a钢板的生产工艺：(l)SA542TypeDCL4a钢板是一种低磷钢板，采用电弧炉+精炼炉+模铸工艺炼钢并制备钢锭, 为保证钢液中P含量，控制电弧炉出钢后钢液中P<0.004%,控制精炼炉脱P后P<0.002%, 为保证钢板探伤合格率，钢液保持抽真空时间N20min,抽真空后静置时间NlOmin。

2、SA553M Type II 钢板执行标准：SA-553/SA-553M (与ASTM 标准A553/A553M-15 完全等同)3、SA553M Type II钢板交货状态：a、淬火硬化一一钢板加热到1475〜1700团(800〜925回)温度范围内，并在此温度下保温足够时间，以便钢板全厚度达到均匀的温度，然后在液体介质中淬火。

b、同火一一钢板在1050〜1175团(565〜635团)温度范围内同火，并在此温度下保温至少30min/in.(1.2min/mm)壁厚，但不得少于15min,并在空气中冷却或水淬，冷却速度不小于300回/h (1650/h) o在回火处理之前，钢板可进行一次中间热处理，即将钢板加热到团型为1165-12900 (630~7000),团型为1185〜1310团(640〜7100)温度范围内，并在此温度下保温至少lh/in.(2.4min/mm)壁厚，但不得少于15min；然后若是厚度大于5/8in. (16mm)的钢板，则水淬到低于300回(150回),若是厚度不大于5/8in. (16mm)的钢板，则空冷或水淬到低于300团(150(21) o注：中间热处理的目的是提高伸长率和缺口冲击韧性，并降低对应变时效脆化和回火脆化的敏感性。

它可由材料生产厂选择实施，也可由需方规定。
