GB/T 3280 关键条款解读:表面代号、尺寸公差与检验

GB/T 3280 是国标冷轧不锈钢板带核心标准。采购重点核对表面代号、尺寸公差(引用 GB/T 708)、力学性能与检验规则。
GB/T 3280 是国内冷轧不锈钢板带的常用标准,关键条款:
1) 牌号与成分:以 06Cr19Ni10 等统一数字代号表示,成分范围见标准;与 EN/ASTM 对照时注意 Ni、Mo 范围差异。 2) 表面代号:2B、BA、No.4 等,代号定义与外观要求见标准;外观验收建议封样比对。 3) 尺寸公差:厚度、宽度、长度公差引用 GB/T 708 等标准;合同要写明公差等级(普通级/较高级)。 4) 力学性能:抗拉、屈服、延伸率等按牌号与交货状态规定;冷作硬化状态另有要求。 5) 检验规则:批次、抽样、复验与判定规则;必要时附加晶间腐蚀、表面质量要求。 6) 包装与标识:标准对包装、标志有要求,出口项目还需符合客户或目的国要求。
采购提示:国内项目常在合同写 "304,GB/T 3280,2B,厚度公差较高级",把牌号、标准、表面、公差等级四件事写全,验收最清晰。
