Stainless steel annealing

Heat treatment of stainless steel is a sequence of heating to temperatures below melting point, followed by controlled cooling, producing structural modifications in the material. At Inoxveneta, two types of annealing are normally applied to stainless steel products subjected to cold-forming processes such ashydroforming: – Recrystallization annealing (860°C – 930°C), usually applied to ferritic stainless grades; – Solution annealing (1000°C – 1050°C), applied to austenitic stainless steels. A good outcome of any heat treatment process needs corrrect speed andexposure time at the right temperatures, normally applied under gas protection; speed of the cooling phase is no less important. Properly performed heat treatment removes residual tension within the material, dissolves carbides into the crystal structure and enhances corrosion resistance. Inoxveneta applies annealing with linear and/or batch furnace solutions in protected atmosphere.
