Overview

SIST EN 4337:2002 is a European Standard developed by CEN that specifies requirements for the aerospace-grade heat resisting alloy NI-WH8901 (NiCr16Ti3Mn2) used as filler metal in welding applications. This standard covers the chemical composition, manufacturing process, form, and mechanical properties for wire and rod forms of the filler metal. It ensures consistent quality and performance of this specialized nickel-chromium alloy in demanding aerospace welding processes.

The standard was prepared by the European Association of Aerospace Manufacturers (AECMA) and harmonized across multiple European countries. It forms part of a series dedicated to metallic materials for aerospace use, focusing on heat-resistant alloys specifically suited for structural and engine components subjected to high temperatures.

Key Topics

• Material Composition: Specifies the chemical makeup of NI-WH8901 alloy, including limits on elements such as Carbon (max 0.08%), Chromium (min 16%), Titanium (approx. 3%), and Manganese (approx. 3%).
• Forms Covered: Defines wire and rod forms as the delivery condition for the welding filler metal.
• Manufacturing Process: Details cold drawing as the method of production after air melting and vacuum refining.
• Delivery Requirements: Calls for cold drawn and annealed material delivered under specified conditions.
• Mechanical Properties: While specific strength or elongation values are not detailed in the excerpt, the standard references EN 3879 for technical specifications including stress, hardness, and tensile properties.
• Testing and Inspection: Refers to related standards for inspection criteria covering dimensional accuracy, batch uniformity, residual stresses, and defect assessments.
• Heat Treatment: Addresses use and delivery condition codes concerning heat treatment protocols.
• Qualification: Requires product qualification programs in line with EN 2043 to be agreed upon between manufacturer and purchaser, ensuring application-specific suitability.

Applications

SIST EN 4337:2002 is essential for:

• Aerospace Manufacturing: Welding and repair of components subjected to high operational temperatures, such as turbine blades, engine parts, and exhaust systems.
• High-Temperature Structural Components: Utilization where heat resisting filler metals are critical to maintaining structural integrity under thermal stress.
• Maintenance and Repair: Providing a standardized filler metal option for aerospace weld repairs where heat resistance and corrosion resistance are paramount.
• Welding Process Standardization: Guiding engineers and manufacturers in selecting and verifying filler metal materials in compliance with aerospace safety and quality standards.

By adhering to EN 4337, aerospace industries ensure reliable performance, safety, and longevity of welded assemblies exposed to extreme heat.

Related Standards

SIST EN 4337:2002 is part of the aerospace metallic materials standards and references several other related standards including:

• EN 3879: Aerospace series – Metallic materials – Filler metal for welding – Technical specification. Provides detailed mechanical and chemical requirements for filler metals.
• EN 2043: General requirements for qualification of semi-finished products excluding forgings and castings.
• EN 4258: Outlines the general organization and linkage between different EN metal standards in aerospace applications.
• EN 4500-3: Rules for drafting and presentation of material standards for heat resisting alloys, ensuring consistent documentation across standards.

Compliance with these interconnected standards ensures full coverage of quality, testing, and application requirements essential for aerospace heat resisting alloys used as welding filler metal.
