Stainless SteelsStainless steels are iron-based alloys containing at least 10.5% Chromium. They achieve their unique stainless properties through the formation of an invisible and adherent Chromium-rich oxide film. Alloy 347 is a versatile austenitic stainless steel with a face-centered cubic structure. It is essentially non-magnetic in the annealed condition and can only be hardened by cold working. The addition of Niobium suppresses grain boundary Chromium Carbide precipitation, enhancing the material's stability and performance.
