Full title and description

ISO/TR 13393:2009 — Welding consumables — Hardfacing classification — Microstructures. A Technical Report that proposes a systematic designation and classification system for microstructures of hardfacing deposits produced by fusion welding processes; includes designation rules for consumable type, intended use, alloy base (iron, nickel, copper, cobalt, tungsten carbide, etc.) and microstructure groupings, with illustrative descriptions and informative annexes.

Abstract

ISO/TR 13393:2009 proposes a system for classifying hardfacing microstructures deposited by fusion welding processes. The report gives summary designators for iron‑base and non‑ferrous microstructures, identifies groups in composition/structure diagrams, and provides guidance on wear types, factors governing wear resistance and practical considerations for selection of hardfacing consumables.

Scope

This Technical Report establishes a classification and designation system for microstructures in hardfacing deposits laid down by fusion welding processes. It covers both iron‑base and non‑ferrous (Co, Ni, Cu, W‑bearing) hardfacing deposit types, presents microstructural group definitions and examples, and provides informative annexes on wear types, wear severity factors, wear‑resistance considerations and test methods. The classification is informative (technical report) and intended to support specification, selection and communication about hardfacing consumables.

Key topics and requirements

• Designation system for hardfacing deposits indicating consumable form, use (hardfacing), alloy base and microstructure type (ferrous and non‑ferrous groups).
• Summary of designators for iron‑base microstructures and diagrams to help identify microstructural groups.
• Descriptions of non‑ferrous microstructure groups (cobalt, nickel, copper and tungsten‑carbide‑bearing deposits).
• Informative annexes: types of wear, factors affecting wear severity, guidance on wear resistance and common abrasive‑wear test methods.
• Practical guidance for selection and specification of hardfacing consumables based on microstructure and expected wear mechanisms.

Typical use and users

Used by welding engineers, materials engineers, consumable manufacturers, maintenance and wear‑protection specialists, and standards committees to classify and specify hardfacing deposits; useful in procurement, technical datasheets, failure analysis and R&D where communication about deposit microstructure and expected wear performance is required.

Related standards

Developed by IIW in liaison with ISO/TC 44/SC 3; cross‑references to national standards and related ISO/IIW guidance appear in informative annexes. It is an informative Technical Report intended to complement standards on welding consumables, filler metals and wear testing methods.

FAQ

Q: What is this standard?

A: ISO/TR 13393:2009 is a Technical Report from ISO that proposes a classification and designation system for microstructures of hardfacing deposits produced by fusion welding processes; it is informative (not a prescriptive normative standard).

Q: What does it cover?

A: It covers designation rules and summaries for iron‑base and non‑ferrous hardfacing microstructures, identification diagrams, descriptions of microstructural groups, and informative guidance on wear types, factors affecting wear resistance and relevant test methods.

Q: Who typically uses it?

A: Welding and materials engineers, manufacturers of welding consumables and hardfacing products, maintenance/specification engineers dealing with wear protection, and technical committees referencing microstructure‑based classifications.

Q: Is it current or superseded?

A: The document was published in 2009 and was reviewed and confirmed in 2014; ISO lists the Technical Report as confirmed (current) as of the last ISO review. Users should check ISO or national bodies for any later revisions before relying on the document for new specifications.

Q: Is it part of a series?

A: It is a stand‑alone Technical Report developed with input from the International Institute of Welding (IIW) and referenced alongside other ISO/IIW documents on welding consumables and wear testing; informative annexes include cross‑references to national standards.

Q: What are the key keywords?

A: Hardfacing, welding consumables, microstructure classification, wear resistance, filler metals, cobalt/nickel/tungsten carbide deposits.
