Company Profile

Stainless SteelsStainless steels are iron-based alloys containing at least 10.5% chromium. Their stainless characteristics are achieved through the formation of an invisible and adherent chromium-rich oxide film. Alloy 347 is a versatile, general-purpose austenitic stainless steel with a face-centered cubic structure. In the annealed condition, it is essentially non-magnetic and can only be hardened by cold working. The addition of niobium suppresses grain boundary chromium carbide precipitation, enhancing its stability.
