英文名称：Welding consumables — Covered electrodes for manual metal arc welding of stainless and heat-resisting steels — Classification

发布日期：2023-08

标准范围

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.
