A method for manufacturing of steel tube from a long steel strip, including providing a length of steel strip material to the process, forming a tube of the steel strip material, welding the formed tube in longitudinal direction, giving the tube a heat treatment wherein the mentioned steps are performed in one continuous in-line manufacturing line and the heat treatment includes a heating regime such that in successive cross-sections of the tube a microstructure is achieved which holds at least 50 vol % austenite and a cooling trajectory to re-introduce ferrite, and/or bainite in desired volume fractions.

Method for the in-line manufacturing of steel tube

A method of producing a shaped aluminum alloy panel, preferably for aerospace or automotive applications, from 5000-series alloy sheet. The method includes: providing a sheet made of 5000-series alloy having a thickness of about 0.05 to 10 mm and a length in the longest dimension of at least 800 mm; and stretch forming the sheet at a forming temperature between &#x2212;100&#xb0; C. and &#x2212;25&#xb0; C., to obtain a shaped aluminum alloy panel. A shaped article formed by the above method is also provided.
