Welding consumables — Tubular cored electrodes and rods for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels — Classification

ISO 17633:2017 specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of core, shielding gas, welding position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels. ISO 17633:2017 is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type. a) Clauses, subclauses, and tables which carry the suffix letter "A" are applicable only to products classified using the system based upon nominal composition. b) Clauses, subclauses, and tables which carry the suffix letter "B" are applicable only to products classified using the system based upon alloy type. c) Clauses, subclauses, and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all products classified in accordance with this document. ISO 17633:2017 does not use pulsed current for determining the product classification.

Produits consommables pour le soudage — Fils et baguettes fourrés pour le soudage à l'arc avec ou sans protection gazeuse des aciers inoxydables et des aciers résistant aux températures élevées — Classification

ISO 17633:2017 spécifie les exigences de classification des fils et baguettes fourrés de flux ou de métal, en fonction de la composition chimique du métal fondu hors dilution, du type fourrage, du gaz de protection, de la position de soudage et des caractéristiques mécaniques du métal fondu hors dilution, fils et baguettes étant destinés au soudage à l'arc avec ou sans protection gazeuse des aciers inoxydables et résistant aux températures élevées. ISO 17633:2017 est une norme mixte permettant une classification utilisant un système basé sur la classification d'après la composition nominale ou utilisant un système d'après le type d'alliage. a) Les articles, paragraphes et tableaux qui portent la lettre «A» ne sont applicables qu'aux produits classifiés selon le système basé sur la composition nominale. b) Les articles, paragraphes et tableaux qui portent la lettre «B» ne sont applicables qu'aux produits classifiés selon le système basé sur le type d'alliage. c) Les articles, paragraphes et tableaux qui ne portent ni la lettre «A» ni la lettre «B» sont applicables aux fils fourrés pour le soudage à l'arc classifiés conformément au présent document. ISO 17633:2017 n'utilise pas le courant pulsé pour la détermination de la classification des produits.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
This document provides a classification system for tubular cored electrodes and rods for welding stainless
and heat resisting steels.
It recognizes that there are two somewhat different approaches in the global market to classifying a given
tubular stainless steel welding consumable, and allows for either or both to be used, to suit a particular
market need. Application of either type of classification designation (or of both, where suitable) identifies a
product as classified in accordance with this document. The classification in accordance with system A was
mainly based on EN 12073:1999 which has been withdrawn and replaced by this standard. The classification
in accordance with system B is mainly based upon standards used around the Pacific Rim.

all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shielded and non-
gas shielded metal arc welding of stainless and heat-resisting steels.
This document is a combined standard providing for classification utilizing a system based upon nominal
composition or utilizing a system based upon alloy type.
a) Clauses, subclauses, and tables which carry the suffix “System A” are applicable only to products
classified using the system based upon nominal composition.
b) Clauses, subclauses, and tables which carry the suffix “System B” are applicable only to products
classified using the system based upon alloy type.
c) Clauses, subclauses, and tables which do not have either the suffix “System A” or “System B” are
applicable to all products classified in accordance with this document.
