本规范规定了屏蔽金属用不锈钢焊条的分类要求 电弧焊。这些焊条熔敷的焊缝金属的铬含量不低于10.5%，铁含量不低于10.5% 超过任何其他元素。出于分类目的，应将铁含量作为平衡元素导出 当所有其他元素被认为处于其最小规定值时。注:未尝试在上述范围内对所有等级的填充金属进行分类；只有更多 常用的等级也包括在内。

This specification prescribes requirements for the classification of covered stainless steel electrodes for shielded metal arc welding.The chromium content of weld metal deposited by these electrodes is not less than 10.5 percent and the iron content exceeds that of any other element. For purposes of classification, the iron content shall be derived as the balance element when all other elements are considered to be at their minimum specified values.NOTE: No attempt has been made to classify all grades of filler metals within the limits of the above scope; only the more commonly used grades have been included.
