Description

2.4631 (Alloy 80A) is a nickel-chromium alloy with additions of titanium and aluminium, which enable it to be strengthened by precipitation hardening. This grade is supplied in the solution treated condition for ease of machinability, but an aging treatment will give the material very high mechanical properties, an outstanding resistance to creep at service temperatures up to 815ºC (1500ºF) and a high resistance to fatigue under very arduous conditions. It shows the following features and properties:

Excellent corrosion resistance

Outstanding creep resistance up to 815ºC

Excellent mechanical properties obtained via aging

Good machinability

Formability and weldability
