Stainless SteelsStainless steels are iron-based alloys containing a minimum of 10.5% Chromium. This essential component imparts their distinctive stainless characteristics by forming a resilient, invisible Chromium-rich oxide layer. Alloy 347 is a versatile austenitic stainless steel boasting a face-centered cubic structure. In its annealed state, it remains virtually non-magnetic and can only be hardened through cold working. The addition of Niobium effectively suppresses grain boundary Chromium Carbide precipitation, enhancing the material's performance.
