1.4564 (WL 1.4564-1 : 1977-12) 1.4564 1.4564 WL 1.4564-1 : 1977-12 Valid Germany 1.1.2 ≤ 315 1)
1) Remark: The ultra high-strength precipitation-hardening stainless CrNiAl steel for aerospace applications can be used up to 315 °C and is suitable for welding. It achieves almost similar corrosion resistance as 18/8 steel (1.4314). Application: - supersonic aircraft skin panels for wing, tail and fuselage
