标准解读

《GB/T 713-2014 锅炉和压力容器用钢板》与《GB 713-2008 锅炉和压力容器用钢板》相比,在内容上有若干重要调整。首先,标准编号从GB变更为GB/T,这意味着该标准由强制性国家标准转变为推荐性国家标准。其次,对于材料牌号进行了部分更新或删除,例如新增了一些适应更高要求的钢材牌号,同时也取消了某些不再适用的老牌号。再者,针对化学成分的要求有所调整,包括但不限于对碳、锰等元素含量范围做出更严格规定。此外,力学性能指标方面也做了相应修改,比如提高了某些牌号钢板的屈服强度下限值。同时,增加了对钢板表面质量及尺寸公差的新要求,以满足现代工业对产品质量日益增长的需求。在试验方法上,《GB/T 713-2014》引用了最新的相关国家标准,并细化了部分检测项目的具体操作流程。最后,关于标志、包装等方面也有细微变动,更加注重信息标识清晰度以及运输过程中产品保护措施的有效性。
