Overview
EN 4318:2025 is a European standard developed by CEN that defines the technical requirements for the aerospace-grade heat-resisting alloy X6NiCrTiMoV26-15 (W.nr 1.4980). This consumable electrode remelted alloy undergoes solution treatment and precipitation treatment to produce bars and sections with diameters up to 100 mm. The standard mandates a minimum tensile strength (Rm) of 960 MPa, ensuring the material's high-performance characteristics essential for aerospace applications. This updated version supersedes EN 4318:2007 and aligns with the specifications of the aerospace metallic materials series, providing stringent quality controls to meet demanding aerospace industry needs.
