Company Profile

Stainless steelsStainless steels are iron-based alloys containing at least 10.5% Chromium, known for their exceptional corrosion resistance due to the formation of a tenacious and invisible Chromium-rich oxide film. Among these, Alloy 347 stands out as a versatile austenitic stainless steel, characterized by a face-centered cubic structure. It is essentially non-magnetic in its annealed state and can only be hardened through cold working processes. Enhanced with Niobium, this alloy effectively suppresses grain boundary Chromium Carbide precipitation, ensuring superior durability and performance.
