2010年11月10日,国家质检总局发布《关于执行〈承压设备用不锈钢板及钢带〉(GB 24511—2009)有关要求的通知》。通知称:《承压设备用不锈钢板及钢带》(GB 24511—2009)已于2009年10月30日发布,并于2010年6月1日实施,该标准是锅炉压力容器专用的不锈钢板及钢带标准。同时《不锈钢热轧钢板和钢带》(GB/T 4237—2007)中的材料不能继续用于锅炉压力容器制造。国家质检总局将陆续对许可证中含GB/T 4237—2007标准的钢板(带)制造单位按照GB 24511—2009进行制造能力确认。
On November 10, 2010, AQSIQ issued the Notice on the Implementation of the Requirements for Stainless Steel Plates and Steel Bars for Pressure-Suppressing Equipment (GB 24511-2009). The circular said: “stainless steel plate and strip for pressure equipment” (GB 24511-2009) was released on October 30, 2009 and implemented on June 1, 2010, which is a stainless steel plate for boiler pressure vessels And steel standards. At the same time, “stainless steel hot-rolled steel sheet and strip” (GB / T 4237-2007) of the material can not be used for boiler pressure vessel manufacturing. AQSIQ will continue to permit the plate with GB / T 4237-2007 standard (strip) manufacturing units in accordance with GB 24511-2009 manufacturing capacity to confirm.
