The SDINOX brand at the SOLDAMAN stand

SD INOX is the specialist in PICKLING, PASSIVATING and ELECTROPOLISHING that the industry needs

WHAT IS STAINLESS STEEL? It is a ferrous alloy containing a minimum of 10% chromium which, under optimal conditions, resists corrosion—always localized—better than ordinary carbon steel. The different types of stainless steel, and their alloys, adapt their behavior to different corrosive substances and mechanical stresses. WHAT MAKES STAINLESS STEEL STAINLESS? Generally speaking, without going into details, the answer is simple: an oxide layer forms on the surface of the material, either spontaneously between the chromium in the metal and oxygen in the air (within 48 hours), or through forced passivation with chemicals (within 15 minutes). If this protective layer is damaged, it regenerates as soon as it comes into contact with oxygen in the air, but if a corrosive substance is also present, unwanted oxidation begins. It is very important to prevent and treat contaminants introduced during workshop processing, and their effects, to ensure proper passivation. At SD INOX, this is achieved through pickling (removal of dirt, adhesive residue, grease, other metals, rust, stains, and marks of all kinds). The subsequent and final passivation process provides the perfect finish.
