BS EN ISO 3581:2023 - TC

This standard BS EN ISO 3581:2023 - TC Tracked Changes. Welding consumables. Covered electrodes for manual metal arc welding of stainless and heat-resisting steels. Classification is classified in these ICS categories:

• 25.160.20 Welding consumables

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.
