<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;">三、常用材料对照</p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;">通常来讲钢材分为：板材、管材、棒材和锻件。另外同一类别根据国家不同又有不同的标准。那么<strong style="color: blue;"><span style="color: green;">SA387Gr11CL2</span></strong>美标板材板材对应的国标板材以及对应的管材、棒材、锻件又分别是什么呢？</p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;">美标钢板<strong style="color: blue;">SA387Gr11CL2</strong>对应的国标板材为：GB/T 713-2014锅炉和压力容器用钢板<strong style="color: blue;"><span style="color: green;">14Cr1MoR</span><span style="color: green;">；</span></strong><span style="color: green;">对应的美标钢管：</span><strong style="color: blue;"><span style="color: green;">SA335 P11</span><span style="color: green;">,</span></strong><span style="color: green;">对应国标管材：GB/T 9948 12Cr1Mo；对应美标锻件ASTM A182 F11CL1/CL2,国标锻件：NB/T 47008 14Cr1Mo</span><strong style="color: blue;"><span style="color: green;">。</span></strong><span style="color: green;">此外</span><strong style="color: blue;"><span style="color: green;">SA691</span></strong><span style="color: green;">高温、高压用电熔焊碳钢和合金钢管标规定的</span><strong style="color: blue;"><span style="color: green;">1¼CR</span></strong><span style="color: green;">钢管级别</span><strong style="color: blue;"><span style="color: green;">（1¼%铬、½%钼）</span></strong><span style="color: green;">对应的钢板原材料就是SA387Gr11CL2。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;">四、常见尺寸及产地</p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;">SA387Gr11CL2</strong>常见的订货尺寸为：厚度>=6mm,宽度2000mm、2200mm、2500mm,长度在11000mm-12000mm。当然可以根据客户的要求进行双定尺（指定宽度和长度）期货订轧。</p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;">通常此SA387Gr11CL2钢板国内一二线钢厂基本均可以生产，但市场流通的钢板主要为一下几个钢厂：<strong style="color: blue;"><span style="color: green;">新钢、湘钢、涟钢、营口、山钢</span></strong>。通常此类钢板的<strong style="color: blue;"><span style="color: green;">订货批量为400吨起订</span></strong>。大部分客户除非承接较大项目，否则在小批量情况下只能寻求现货或者通过拼单方式进行期货订轧。市场流通的现货库存钢板执行的<strong style="color: blue;"><span style="color: green;">厚度偏差为A578B/C</span><span style="color: green;">。</span></strong><span style="color: green;">因为市场</span><strong style="color: blue;"><span style="color: green;">SA387Gr11CL2</span></strong><span style="color: green;">现货库存较14C1MoR现货库存充足，导致14CrMoR钢板价格较</span><strong style="color: blue;"><span style="color: green;">SA387Gr11CL2</span></strong><span style="color: green;">高。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;">五、此类钢板的主要用途</p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;">由钢板的名称我们不难看出“压力容器用<strong style="color: blue;"><span style="color: green;">珞（luò）-</span></strong>钼合金钢板”主要应用在压力容器设备制造上，主要有：塔器、反应釜、封头、加氢反应器。主要应用的行业为：石油化工行业。由于SA387Gr11CL2是SA691 1¼钢管对应的板材，所以对于SA691焊管，可以应用到的电厂（火力发电厂）四大管道当中，主要应用的产品为焊管、弯头、法兰、三通等。</p>
