GB/T 3280、ASTM A240 与 EN 10088-2 对照(冷轧不锈钢板卷)

冷轧板卷常用 GB/T 3280、ASTM A240 与 EN 10088-2。表面代号(2B/BA/No.4)与尺寸公差的引用标准差异是验收重点。
冷轧不锈钢板卷的常用标准为 GB/T 3280、ASTM A240 与 EN 10088-2。对照时除了牌号,还要关注表面与尺寸标准:
| 项目 | GB/T 3280 | ASTM A240 | EN 10088-2 | |---|---|---|---| | 产品 | 冷轧不锈钢板/带 | 板带(冷热轧) | 冷轧/热轧板带 | | 表面 | 2B/BA/No.4 等(国标代号) | No.1/2B/BA/No.4 等 | 2B/2D/2H/2R 等(EN 文字代号不同) | | 尺寸公差 | GB/T 708 等 | A480(通用要求) | EN 10131 / EN 10051 | | 牌号 | 06Cr19Ni10 等 | 304/316L 等 | 1.4301/1.4404 等 |
验收要点:
1) 明确"表面代号 + 尺寸公差标准",例如 304 2B per ASTM A240 + A480,或 1.4301 2B per EN 10088-2 + EN 10131; 2) EN 的 2D/2B/2R 与国标 2B/BA 并非完全一一对应,外观验收建议封样比对; 3) 冷轧板卷还要关注板形(波浪、瓢曲)、厚度公差与卷重/内径等交货条件。
合同里把牌号、表面、尺寸标准、公差等级写全,是最有效的防争议方式。
