Nimonic 80A

UNS N07080

 

GENERAL PROPERTIES

Nimonic alloys are primarily composed of nickel and chromium. These alloys are known for their high-temperature low-creep and high performance. Additives like aluminium, carbon and titanium are infused into the alloy. The Nimonic alloy was first developed in 1940 in England. NIMONIC alloys available commercially are Nimonic 75, Nimonic 80A, 81, 86, Nimonic PE11 and 16.

Nimonic alloy 80A is a wrought, age-hardened alloy that is strengthened by additives like titanium, aluminium and carbon. It is manufactured by high-frequency melting and casting in air. It is similar to Nimonic alloy 75.

 

RESISTANCE TO CORROSION

It has good corrosion and oxidation resistance. The creep rupture and tensile properties are high at 815°C (1500°F).

WELDING

Nimonic alloy 80A can be welded using common techniques, using a matching filler metal. A prerequisite for welding is that the metal should be solution treated. Fusion welding by tungsten inert gas welding and metal inert gas welding will be suitable for this alloy.

 

HEAT TREATMENT

Nimonic 80A alloy can be heat treated at 1079°C (1975°F) for 8h and air cooled.
