API Grade 60 Heat Treatments

  • The plates shall be quenched and tempered by cooling to a temperature below 1000°F (538°C) after rolling, reheating to a temperature between 1500°F (815°C) and 1700°F (925°C) to produce an austenitic structure, holding a sufficient time to attain uniform temperature throughout the material, quenching in a suitable liquid medium and tempering at 1050°F-1300°F (565°C-705°C)
  • Heated over 595°C (1100°F) or more than 38°C (50°F) below the original quench or fabrication aging temperature (if applicable) due to the risk of developing irreversible and significant loss of strength and stiffness.
