Product Description

Temperatures 815°C Cold Rolled Strip W.Nr. 2.4631 Nickel-Chromium Alloy


W.Nr. 2.4631 is a wrought, age-hardenable nickel-chromiumalloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded.
Electroslag refined material is used for forms to be forged. Vacuum refined versions are also available.

W.Nr. 2.4631 (Nimonic 80A) has been replaced by the Nimonic 90 and Inconel X-750, but is still widely used in nuclear power field due to its low cobalt content.
