The alloy is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.
