Overview

SIST EN 4336:2004 defines the requirements for the use of Steel FE-WA3801 (X4CrNiMn20-10-2) as a filler metal specifically designed for welding applications in the aerospace sector. This European standard details specifications for both wire and rod forms of this particular steel alloy, focusing on its use for critical welding operations in aircraft and aerospace component manufacturing and maintenance. The document serves as a reference for manufacturers, suppliers, and quality assurance professionals involved in aerospace projects where the reliability of welded joints is paramount.

Key Topics

• Material Specification: Steel FE-WA3801 (X4CrNiMn20-10-2) is the designated material, offering a precise chemical composition suited for aerospace environments. The standard emphasizes requirements for mechanical properties and alloying elements.
• Product Forms: The standard applies to filler metals supplied as either cold drawn wire or rod, providing flexibility depending on the welding application.
• Production and Delivery: It specifies that the filler metal must be air-melted and delivered in a cold drawn and annealed condition, ensuring consistency in quality and performance.
• Quality and Testing: EN 4336 references additional standards (like EN 3879) for technical specifications, product qualification, and batch verification to ensure batch uniformity, absence of external and internal defects, and marking requirements.
• Normative References: The document integrates requirements and guidelines from a series of linked standards concerning metallic materials and aerospace applications.

Applications

SIST EN 4336:2004 is chiefly applicable to:

• Aircraft and Aerospace Component Manufacturing: Used in the assembly, fabrication, and repair of aircraft structures where welded joints must meet stringent safety and durability standards.
• Maintenance and Repair: Ideal for repair processes involving critical welded joints on aircraft and space vehicles.
• Supplier Evaluation and Audit: Manufacturers and suppliers are evaluated for compliance with this standard, ensuring that welding consumables supplied to the aerospace industry meet all required specifications.

Practical applications benefit from the standardization of filler metals, minimizing variability and supporting the traceability of critical welding materials in safety-sensitive environments. The standard also assists procurement teams in specifying the correct filler materials and supports quality control departments in verifying material conformance.

Related Standards

SIST EN 4336:2004 references and works in conjunction with several other important aerospace standards, including:

• EN 2043: Aerospace series - Metallic materials - General requirements for semi-finished product qualification
• EN 3879: Aerospace series - Metallic materials - Filler metal for welding - Technical specification
• EN 4258: Aerospace series - General organization of standardization of metallic materials
