HYDROGEN ANNEALING
Annealing is a process of heating, soaking and controlled cooling of coil in a non-oxidizing atmosphere. Metallurgically, the annealing process relieves the stresses developed by Cold Rolling and renders the strip soft and restores its ductility and formability.
Hydrogen annealing furnaces use 100% hydrogen atmosphere, resulting in a clean and bright surface of the strip. The automated feature of furnaces at Hero Steels helps to maintain accuracy in operation so as to deliver consistent quality
