Abstract
A method for producing a tube of a nickel-based alloy tube which comprises the steps of hot working a nicked-based alloy casting into a pretubular-shaped workpiece or into a cylindrical bar, trepanning the cylindrical bar or machining an inner diameter of the pretubular-shaped workpiece to obtain a tubular workpiece, and cold working the tubular workpiece. The hot working comprises one of: rolling, forging, and a combination thereof. The cold working comprises flow forming or pilgering. A nickel-based alloy tube produced with the method comprises an outer diameter greater than or equal to 60.3 mm, an average wall thickness greater than or equal to 2.8 mm, and less than or equal to 70 mm.
