NF EN ISO 17633
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.

Le présent amendement corrige la norme NF EN ISO 17633:2018 qui spécifie les exigences de classification des fils et baguettes fourrés de flux ou de métal destinés au soudage à l'arc des aciers inoxydables et résistant aux températures élevées, en fonction de la composition chimique du métal fondu hors dilution, du type de fourrage, du gaz de protection, de la position de soudage et des caractéristiques mécaniques du métal fondu hors dilution. Deux systèmes de classification sont proposés, l'un basé sur la composition nominale (système A) et l'autre basé sur le type d'alliage (système B). Le présent amendement corrige les teneurs Mn et Si pour les désignations 16 8 2, 19 9 H et 25 4, dans le Tableau 1A qui donne les symboles et exigences de la composition chimique du métal fondu hors dilution dans le système de classification basé sur la composition nominale.
