Aeroval AN5

Material Description

AN5 is an iron-nickel-chromium alloys. Elements like Al and Ti in austenitic structures make this alloy aged-hardenable by appropriate heat treatment with increase of strength and hardness.  Addition of Molybdenum provides high-temperature stability and reduce high-temperature creep.

This alloy has greater resistance to high temperation than low-alloy steel and stainless steel and shows good mechanical properties at temperatures up to 700°C.


For their high-temperature strength and corrosion resistance this alloy is used in aerospace industry, power generation (component of aircraft and industrial gas turbines, shaft, vanes, blades and jet engines), automotive industry (fasteners, bolts and screws, springs, afterburners), thermal processing, non-magnetic cryogenic equipment.

Corrosion and Oxidation Resistance

The corrosion resistance of this alloy is excellent up to 700°C; it shows an oxidation resistance similar to AISI310 up to 860°C.

It maintains good corrosion and oxidation resistance for continuous service to 815°C, intermittent to 980°C.  Nevertheless its corrosion resistance to sulfuric and phosporic acid is moderate. Its aqueous corrosion resistance is similar to 316L.

Cold Working

After the solution heat treatment material achieves UTS 680-690 N/mm², in this condition it can be cold-formed by standard processes.
