14Cr17Ni2 steel forged bar and annealing method thereof

The invention belongs to the technical field of heat treatment of metal materials, and discloses a 14Cr17Ni2 steel forged bar and an annealing method thereof. The annealing method comprises the steps that an annealing furnace is heated to the material waiting temperature; the bar is forged and then subjected to hot delivery annealing; annealing the bar for the first time to obtain a primary annealed material; carrying out secondary annealing on the primary annealing material to obtain a secondary annealing material; and carrying out third annealing on the secondary annealing material to obtain a product. According to the method, by controlling the furnace entering time of the forged bar after forging, improving the annealing process and conducting annealing treatment for three times, it can be guaranteed that the structure of the forged bar is completely transformed, residual thermal stress and structural stress in the forged bar are eliminated, the forged bar is prevented from exploding, and losses are reduc
