Overview

SIST EN 4330:2004 is a European standard established by CEN that defines the specifications for Steel FE-WA4802 (X8CrNiMn27-22-2) used as filler metal in welding applications within the aerospace industry. This standard covers both wire and rod forms of the material and ensures the product meets stringent aerospace quality and performance requirements.

Designed under the auspices of the European Association of Aerospace Manufacturers (AECMA), SIST EN 4330:2004 aims to standardize welding filler metals for aerospace applications, ensuring compatibility, safety, and reliability in critical aerospace components fabrication and repair.

Key Topics

Material Specifications

• Steel Type: FE-WA4802 (X8CrNiMn27-22-2)
• Chemical Composition: Ensures precise control over elements like Carbon, Silicon, Manganese, Phosphorus, Sulfur, Chromium, Molybdenum, Nickel, Copper, and Iron to maintain aerospace-grade quality.
• Manufacturing Process: Cold drawn and annealed to optimize mechanical properties.

Form and Dimensions

• Supplied as welding filler metal in the form of wire and rod.
• Strict dimensional tolerances to guarantee uniformity and fit for aerospace welding applications.

Mechanical and Physical Properties

• Mechanical characteristics such as proof stress, tensile strength, elongation, hardness, and shear strength are defined to ensure withstandability under aerospace operational stresses.
• Delivery conditions specify heat treatment and annealing processes to stabilize the metal.

Quality and Testing

• Conformance with related standards like EN 3879 for residual stresses, internal defects, marking, and dimensional inspection.
• Batch uniformity and product qualification per EN 2043, ensuring consistent quality across production lots.
• Testing regimes include mechanical strength and defect inspection tailored for aerospace safety.

Applications

SIST EN 4330:2004 filler metals are explicitly designed for aerospace manufacturing and maintenance operations where high-strength, corrosion-resistant, and reliable welds are critical. Common applications include:

• Aerospace Structural Welding: Joining high-performance steel components in airframe and engine assemblies.
• Repair and Maintenance: Welding filler metal for fixing or retrofitting aerospace parts exposed to extreme operational environments.
• Manufacture of Aerospace Components: Use in fabrication processes requiring exact chemical and mechanical properties to meet aerospace industry specifications.

By standardizing filler metals like Steel FE-WA4802 in wire and rod forms, SIST EN 4330:2004 contributes to safer, more efficient aerospace manufacturing and durability across various flight-critical components.

Related Standards

SIST EN 4330:2004 is part of a broader European aerospace metallic materials series, interconnected with the following key standards:

• EN 2043: Aerospace series – General requirements for semi-finished product qualification.
• EN 3879: Aerospace series – Technical specifications for filler metals used in welding.
• EN 4258: Organization of aerospace metallic material standardization.
• EN 4500-5: Specific drafting rules for steel standards within aerospace metallic materials.

These complementary standards together establish a comprehensive framework governing materials, production processes, testing, and qualification of welding filler metals intended for aerospace applications.
