AISI 347 Stainless Steel Coil

Our AISI 347 Stainless Steel Coils are made from an austenitic chromium-nickel stainless steel with excellent corrosion and heat resistance properties. They’re used in applications requiring a good elevated temperature strength and oxidation resistance up to 870°C, such as in furnace parts, radiant tubes and combustion chambers. These coils come in thicknesses from 0.025mm to 0.50mm with 2 variations to choose from.
