Company Profile

Stainless SteelsStainless steels are iron-based alloys containing at least 10.5% Chromium. The unique stainless characteristics are achieved through the formation of an invisible and adherent Chromium-rich oxide film. Among these, Alloy 347 stands out as a versatile austenitic stainless steel with a face-centered cubic structure. In its annealed state, it is essentially non-magnetic and can only be hardened by cold working. The addition of Niobium effectively suppresses grain boundary Chromium Carbide precipitation, enhancing its performance.
