标准范围

本文件规定了在焊接或热处理条件下，基于全焊缝金属化学成分、焊条覆盖类型和其他焊条性能以及全焊缝金属机械性能的焊条分类要求，用于不锈钢和耐热钢的手工金属电弧焊。本文件是一个组合标准，提供了利用基于根据标称成分分类的系统或利用基于根据合金类型分类的系统进行分类。A）？标有“根据标称成分-A分类”或“ISO？3581-A”的段落和表格仅适用于分类到该系统的产品。b）？标有“按合金类型分类-B”或“ISO？3581-B”仅适用于归入系统产品。c）？不带有任何标签的段落和表格适用于根据其中一个或两个系统分类的产品。附件？B给出了关于焊缝金属铁素体含量的考虑因素的信息。

This document specifies requirements for classification of covered electrodes, based on the all-weld metal chemical composition, the type of electrode covering and other electrode properties, and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of stainless and heat-resisting steels.

This document is a combined standard providing for classification utilizing a system based upon classification according to nominal composition or utilizing a system based upon classification according to alloy type.

a)       Paragraphs and tables which carry the label “classification according to nominal composition-A” or “ISO 3581-A” are applicable only to products classified to that system.

b)       Paragraphs and tables which carry the label “classification according to alloy type-B” or “ISO 3581-B” are applicable only to products classified to that system.

c)        Paragraphs and tables which carry neither label are applicable to products classified according to either or both systems.

Annex B gives information on considerations on weld metal ferrite content.
