Welding consumables - Covered electrodes for manual metal arc welding of stainless and heat-resisting steels - Classification (ISO 3581:2023)
16-08-2023
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 “ISO3581-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 “ISO3581-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.AnnexB gives information on considerations on weld metal ferrite content.
