Company Profile

Stainless SteelsStainless steels are exceptional iron-based alloys containing a minimum of 10.5% Chromium. This vital element enables stainless steels to form an invisible, adherent chromium-rich oxide film, endowing them with their remarkable corrosion resistance. Alloy 347, a versatile austenitic stainless steel, features a face-centered cubic structure and exhibits essentially non-magnetic properties in its annealed state, with the ability to be hardened exclusively through cold working. Enhanced with Niobium, Alloy 347 effectively suppresses grain boundary chromium carbide precipitation, ensuring superior stability and performance in demanding environments.
