ASME Boiler and Pressure Vessel Code An International Code Section II - Part A Ferrous Material Specifications / American Society of Mechanical Engineers / 2023

Heat Treatments

  • All plates shall be heat treated by heating to a suitable <b>austenitizing</b> temperature, holding for a sufficient period of time to attain uniform temperature throughout the thickness, and quenching in a suitable liquid medium by spraying or immersion. The minimum austenitizing temperature shall be 900°C (1650°F). After <b>quenching</b>, plates shall be tempered by heating to a suitable temperature and holding for a period of time of not less than 1.2 minutes/mm of thickness but not less than 1/2 hour. Plates over 100 mm in thickness shall receive a prior heat treatment of <b>normalizing</b> at, or water quenching from, a temperature within the range from 900 to 1010°C (1650 to 1850°F) before the final heat treatment. Plates ordered without the heat treatment shall be furnished in either the <b>stress-relieved or the annealed</b> condition. Minimum stress relieving temperature shall be 565°C (1050°F).
