Valour Alloys Inc., we carry a full inventory and Supply Stainless Steel 347 Flanges products in a variety of sizes widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.

SS 347 Flanges are flange fittings made from stainless steel grade 347, which is a stabilized austenitic stainless steel with the addition of columbium (niobium) and tantalum. These flanges offer excellent high-temperature strength and resistance to intergranular corrosion.

347 flanges are vital components in various industrial applications, particularly in environments that require resistance to high temperatures and corrosive substances. These flanges are made from a specific type of stainless steel known as 347 stainless steel, which is a modified version of the 304 stainless steel with added niobium (columbium). The addition of niobium enhances the material's resistance to intergranular corrosion, making it suitable for high-temperature and high-stress applications.
