1 Scope
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.
