Overview

SIST EN 4339:2002 is a European Standard developed by the Comité Européen de Normalisation (CEN) that specifies the technical requirements for the heat resisting alloy CO-WH4001 (CoCr29W9) used as filler metal in welding applications. This standard covers both wire and rod forms of the alloy specifically tailored for aerospace industry applications. It ensures that the materials meet stringent quality and performance criteria vital for high-temperature resistance and durability in aerospace environments.

The standard was prepared by the European Association of Aerospace Manufacturers (AECMA) and aligns with the broader aerospace metallic material standards series, following the organizational guidelines described in EN 4258 and the drafting rules in EN 4500-3. It is applicable across multiple European countries, making it a harmonized norm for aerospace welding filler metals.

Key Topics

• Material Composition
  SIST EN 4339:2002 details the chemical composition of CO-WH4001 (CoCr29W9), emphasizing elements such as cobalt, chromium, tungsten, nickel, and others that contribute to the alloy’s heat resistance and mechanical properties.

• Forms and Production
  The standard specifies the production methods including cold drawing for wire and rod forms, ensuring consistent physical and mechanical properties essential for welding performance.

• Technical Specifications
  Includes parameters for delivery condition (cold drawn and annealed), heat treatment processes, and dimensional limits to guarantee uniformity and quality.

• Mechanical and Physical Properties
  The standard addresses critical mechanical characteristics such as proof stress, tensile strength, elongation, hardness, shear strength, bending, impact strength, and resistance to residual and internal defects in compliance with EN 3879.

• Testing and Quality Assurance
  SIST EN 4339:2002 references related standards such as EN 2043 for product qualification and EN 3879 for filler metal technical specifications, controlling batch uniformity, marking, dimensional inspection, and defect evaluation.

• Designation and Marking
  Clear identification and traceability of the filler metals are mandated to support aerospace manufacturing and certification processes.

Applications

SIST EN 4339:2002 filler metal products are critical in aerospace welding operations where high-temperature strength, corrosion resistance, and weld integrity are paramount. Typical applications include:

• Aerospace Component Welding
  Used for joining high-temperature resistant components in gas turbines, aircraft engines, and structural assemblies exposed to extreme thermal conditions.

• Repair and Maintenance
  The welding wires and rods compliant with this standard are utilized in maintenance, repair, and overhaul (MRO) activities to restore performance-critical aerospace parts.

• Manufacturing of Heat-Resistant Alloys
  Essential in fabricating parts requiring excellent oxidation and corrosion resistance in demanding aerospace environments.

Implementing SIST EN 4339:2002 ensures that aerospace manufacturers and suppliers comply with stringent quality measures, achieving reliability and safety in welded assemblies exposed to severe operating conditions.
