Available product shapes: Open Die Forgings, Long Products, Semi-Finished Products / Billet, Plates

Product description

High duty parts and components for gas turbines, aerospace engines, nuclear reactors and pumps. Extrusion dies for copper alloys, hot piercing plugs for steel and brass working, forging die inserts, hot shear blades.

Property features

High temperature, precipitation hardening, nickel-base alloy with particularly high hot strength and hot yield strength up to 750°C, and excellent creep behaviour up to 700°C. The markedly higher hot strength compared with normal hot work steels is particularly noticeable when used for hot work tools with high mechanical and thermal stresses. Only air cooling of the tools is permissible.
