Bright annealing treatments can be performed on a wide range of carbon, alloy, stainless steel, and non-ferrous materials.  Bright annealing is typically performed in batch vacuum furnaces and in continuous hydrogen atmosphere belt furnaces, depending on part size and geometry.  The process is typically used with fine surface quality stampings and screw machine parts.  The advantage of bright annealing is the prevention of scale or oxidation on the surface of critical components.  The surface quality and cleanliness of the bright annealed part may exceed that of the raw part.
