ASME SA-542 Type E Class 4a Heat Treatments


  • All plates shall be heat treated by heating to a suitable austenitizing 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 1010°C (1850°F). After quenching, 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 normalizing at, or water quenching from 1010 to 1120°C (1850 to 2050°F), before the heat treatment. Plates ordered without the heat treatment shall be furnished in either the stress-relieved or the annealed condition. Minimum stress relieving temperature shall be 650°C (1200°F).
