HASTELLOY® C22 is a specialty industrial material that provides excellent resistance to intergranular attack, pitting and crevice corrosion and stress corrosion cracking, and is very effective in many applications where a very high level of corrosion resistance is required.

An austenitic alloy, C-22 provides outstanding resistance in static or running marine water for ballast water management and other seawater filtration applications and resists attack in oxidizing and reducing conditions as well as aqueous solutions.

It is an ideal material for use in sintered square wire mesh applications including different types of chemical processes including, wet chlorine, combined oxidizing acids such as nitric acid, formic acid, acetic acid, ferric and cupric chlorides and other chemical conditions.

C-22 is proven for manufacturing pressure vessels and components following ASME boiler and Pressure Vessel Code Section VIII, Division 1 for application temperatures up to 1250oF/677oC. The service temperature for this alloy should be kept below 1250oF.

Common applications for HASTELLOY® C-22 sintered wire mesh include Nutsche filter dryers, pharmaceutical processing, and pressure vessels. We offer HASTELLOY® C-22 sintered wire mesh in 5-layer and 7-layer configurations in flat sheets up to 48”x48” size in various micron ratings.
