<p>是奥氏体和铁素体组织各约占一半的合金钢管。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合金钢管的特点，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合金钢管的475℃脆性以及导热系数高，具有超塑性等特点。与奥氏体合金钢管相比，强度高且耐晶间腐蚀和耐氯化物应力腐蚀有明显提高。双相合金钢管具有优良的耐孔蚀性能，也是一种节镍合金钢管。</p> <p>单品 品名 规格 材质 产地/厂家 地域 价格 (元/吨) 涨跌 报价日期 <br /> 镀锌管 镀锌管 8寸*5 Q235 友发 上海 5580 0&nbsp; 12-05-16 <br /> 镀锌管 镀锌管 6寸*4 Q235 武钢 上海 5390 0&nbsp; 12-05-16<br /> 镀锌管 镀锌管 4寸*3.75 Q235 唐山华岐 上海 5220 0&nbsp; 12-05-16 <br /> 镀锌管 镀锌管 1.5寸*3.25 Q235 金洲 上海 5570 0&nbsp; 12-05-16 <br /> 镀锌管 镀锌管 1寸*3 Q235 江苏国强 上海 5920 0&nbsp; 12-05-16 <br /> 镀锌管 镀锌管 6分*2.5 Q235 江苏国强 上海 5780 0&nbsp; 12-05-16 </p> <p>公司自成立以来，一直把产品质量作为企业生存的根本，把服务质量作为我们成功的桥梁我们衷心希望与广大客户建立业务联系，提供优质服务，同创业，共发展。</p> <p>专业生产：不锈钢板,304不锈钢板,321不锈钢板,316L不锈钢板,<a style="word-spacing:0px;font:medium Simsun;text-transform:none;text-indent:0px;white-space:normal;letter-spacing:normal;background-color:#ffffff;orphans:2;widows:2;webkit-text-size-adjust:auto;webkit-text-stroke-width:0px;" href="http://www.91fgw.com/">厚壁方管</a><span style="display:inline!
