ASTM A 522 Type II 物理性能
ASTM A 522 Type II 热处理
- Quenching and tempering: Quenching in water: 802 ± 14°C (1475 ± 25°F), hold at this temperature for a minimum time of 2.5 min/mm of thickness but in no case less than 30 min; quench by immersion in circulating water. Reheat until the forging attains a uniform temperature within the range from 566 - 607°C (1050 - 1125°F); hold at this temperature for a minimum time of 2.5 min/mm of thickness but in no case less than 30 min; cool in air or water quench, at a rate not less than 167°C/h (300°F/h).
Double Normalized and Tempered: Heat to a uniform temperature of 899°C (1650°F); hold at this temperature for a minimum time of 2.5 min/mm of thickness but in no case less than 30 min; cool in air. Reheat until the forging attains a uniform temperature of 788°C (1450°F); hold at this temperature for a minimum time of 2.5 min/mm of thickness but in no case less than 30 min; cool in air. Reheat to a uniform temperature within the range from 566 - 607°C (1050 -1125°F); hold at this temperature for a minimum time of 2.5 min/mm of thickness but in no case less than 30 min; cool in air or water quench, at a rate not less than 167°C/h (300°F/h).
When stress relieving is to be performed after fabrication, the recommended stress-relieving treatment is as follows: gradually and uniformly heat the steel to a temperature between 552 - 585°C (1025 - 1085°F); hold for a minimum of 2 h for thicknesses up to 25 mm. For thicknesses over 25 mm, a minimum additional holding time in the ratio of 2.5 min/mm of thickness in excess of 25 mm shall be added. Cool at a minimum rate of 167°C/h (300°F/h) to a temperature not exceeding 316°C (600°F).
