Cold-drawn softened. A mild drawing follows the last reduction drawing. tubes can be cold formed within certain limits. Stress Relieved Annealed. A low-temperature stress-relieving heat treatment is carried out after the last drawing pass, which leaves the mechanical properties unchanged and increases the elongation to over 15%. Annealed. tubes are annealed in controlled atmosphere after the last drawing pass. Normalised. tubes are normalised in a controlled atmos-phere after the last drawing pass with a temperature above the upper transformation last drawing pass with ure above the upper tion tubesStructural hollow sections ex hot rolled steel , cold formedThe specialized range of structural square, rectangular and round tubes by Marcegaglia suits the requirements of civil and naval building site equipment sectors, according to cur-rent norms.
