Aeroval AISC

Material Description

Austenitic Stainless Steel stabilised by the addition of Columbium.  Mechanical properties can be increased by cold working only.  AISC exhibits good intergranular corrosion resistance.


AISC can be used for aircraft components as collector rings, exhaust manifolds, expansion joints.  Generally AISC is used for applications subjected to intermittent heating from 450° and 800°C as: fireproof bulkhead, pressure vessels, welded structures, high-temp chemical processing and gas turbine blades.

Corrosion and Oxidation Resistance

Because of the Columbium addition capable to enhance the intergranular corrosion resistance, AISC can be used for many different applications as chemical and oil processing textile manufacturing and food industry. AISC provide a good resistance to scale formation up to 860°C.


AISC can be welded.  If filler metal is requested AWS E/ER347 should be used. Post-weld heat treatment is not strictly needed unless high temperature service is required.
