Description (English):

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.

Abstract

Overview

ISO 17633:2017 - Welding consumables: Tubular cored electrodes and rods for gas shielded and non-gas shielded metal arc welding of stainless and heat‑resisting steels - Classification defines a unified classification system for tubular flux‑cored and metal‑cored electrodes and cored rods used to weld stainless steels and heat‑resisting steels. The standard covers identification, symbols, and requirements based on the all‑weld metal chemical composition, core type, shielding gas, welding position and all‑weld metal mechanical properties in as‑welded or heat‑treated conditions.

Key technical topics and requirements

Two classification systems:
- System A - based on nominal chemical composition (suffix “A”).
- System B - based on alloy type (suffix “B”).
- Clauses/tables are marked with “A” or “B” where applicable; unmarked clauses apply to both.
Product identification symbols: product type (T or TS), chemical composition/alloy designation, core type, shielding gas, and welding position.
All‑weld metal requirements: chemical composition and mechanical property limits for deposits produced under specified deposition conditions.
Core types: classification and descriptions for flux‑cored, metal‑cored and cored rods (detailed in Annexes B and C).
Mechanical testing and test conditions: preheat/interpass considerations, pass sequence, and test specimen requirements (see Clause 6 and normative ISO test references).
Chemical analysis and rounding procedures, requirements for retests and technical delivery conditions (Clauses 7–10).
Ferrite considerations: informative guidance on ferrite content, formation and measurement (Annex D).
Exclusion: pulsed current is not used for classification.

Practical applications

Specification and labeling of filler materials on data sheets and packages for procurement and quality control.
Selection of appropriate tubular cored electrodes/rods for welding stainless and heat‑resisting steels with specific corrosion, high‑temperature or mechanical property needs.
Supporting Welding Procedure Specifications (WPS), qualification testing and acceptance criteria for fabrication and repair.
Useful for manufacturers, welding engineers, fabricators and quality inspectors who need standardized designations and reproducible all‑weld metal characteristics.

Who should use ISO 17633:2017

Welding consumable manufacturers for product classification and marking.
Welding engineers and procedure writers selecting filler metals for stainless and heat‑resisting steel applications.
Procurement/specification teams creating material call‑outs.
Inspectors and labs performing mechanical and chemical verification of weld deposits.

Related standards

ISO 14175 (welding gases), ISO 15792‑1 (all‑weld metal test methods), ISO 6947 (welding positions), ISO 544 (delivery conditions) and ISO 14344 (procurement of filler materials) - referenced in ISO 17633:2017 for test methods, gas definitions and delivery requirements.

Keywords: ISO 17633:2017, tubular cored electrodes, cored rods, stainless steels, heat‑resisting steels, welding consumables, classification, all‑weld metal, flux‑cored, metal‑cored, shielding gas.
