ABS AB/A10 热处理
- Forgings are to be normalized, quenched and tempered.
Cooling prior to heat treatment: After forging and before reheating for heat treatment, the forgings are allowed to cool in a manner to prevent injury and to accomplish transformation.
Annealing: The forgings are to be reheated to and held at the proper austenitizing temperature for a sufficient time to effect the desired transformation and then be allowed to cool slowly and evenly in the furnace until the temperature has fallen to about 455°C (850°F) or lower.
Normalizing: The forgings are to be reheated to and held at the proper temperature above the transformation range for a sufficient time to effect the desired transformation and then withdrawn from the furnace and allowed to cool in air.
Tempering: The forgings are to be reheated to and held at the proper temperature, which will be below the transformation range, but above 580°C (1075°F), and then to be cooled at a rate not exceeding 55°C (100°F)/h until temperature below 315°C (600°F) is reached.
Stress Relieving: Where heat treatment for mechanical properties is carried out before final machining, the forgings are to be stress relieved at a temperature not more than 55°C (100°F) below the previous tempering temperature, but in no case less than 550°C (1025°F). The cooling rate is not to exceed 55°C (100°F)/h until a temperature below 315°C (600°F) is reached. Stress relieving may be used to augment tempering, in order to make final adjustments to the mechanical properties. If the stress relief temperature is within 14°C (25°F) of the final tempering temperature or higher for quenched and tempered steel, mechanical tests are to be made to assure that these temperatures have not adversely affected the mechanical properties of the steel.
Retreatment: The manufacturer may re-heat treat the forging, but not more than three additional times.
