The in-line bright annealing process is mainly used with AISI 300, AISI 400, duplex, superduplex and titanium pipes for various application such as petrochemical, furniture, automotive, food and beverage.
The main goal of the process is the annealing which is responsible of the decreasing of hardness. Due to the lower heating time, a partial solubilisation of chromium carbides obtained with respect to the one reached with traditional furnaces. Consequently the resistance to corrosion is increased, especially in the welded zone.
