Overview
EN 4338:2001 (CEN) defines the requirements for heat-resisting alloy NI‑WH3902 (NiCr25Mo10C) when supplied as filler metal for welding in the form of wire and rod for aerospace use. Prepared by AECMA and approved by CEN in 2001, this standard is part of the EN aerospace metallic materials series and links to the series’ general organization and drafting rules.
Key topics and requirements
- Material designation: NI‑WH3902 (NiCr25Mo10C) - a nickel‑based heat‑resisting alloy specified for welding filler metal.
- Forms covered: wire and rod intended as welding filler metal for aerospace applications.
- Production and melting:
- Method of melting: consumable electrode remelted.
- Method of production: cold drawn.
- Delivery condition: supplied cold drawn and annealed (specified delivery condition).
- Technical and qualification references:
- Product and semi‑finished product qualification are referenced to EN 2043.
- Filler‑metal technical specification and test provisions reference EN 3879.
- Standard drafting and heat‑resisting alloys follow EN 4500‑3 and general organization guidance in EN 4258.
- Quality and inspection: EN 4338 points users to EN 3879 for residual/internal defect inspections, dimensional checks, marking, and batch uniformity (material verification).
- Product qualification: a qualification program is to be agreed between manufacturer and purchaser as described under EN 2043.
Applications and who uses it
