HEAT TREATMENT :

  • Except for Grade 91, all ASTM A387 plates shall be thermally treated either by annealing, normalizing and tempering, or, when permitted by the purchaser, accelerated cooling from the austenitizing temperature by air blasting or liquid quenching, followed by tempering. The minimum tempering temperatures for grades (2, 12 & 11), grades(22, 22L, 21, 21L & 9), grades 5 are respectively 1150°F[620°C], 1250°F[675°C], 1300°[705°C].
  • Grade 91 plates shall be thermally treated, either by normalizing and tempering or by accelerated cooling from the austenitizing temperature by air blasting or liquid quenching, followed by tempering. Grade 91 plates shall be austenitized at 1900 to 1975°F [1040 to 1080°C] and shall be tempered at 1350 to 1470°F [730 to 800°C].

 

INSPECTION AND TEST:

The inspection and tests that shall be alternately performed on ASTM A387 alloy steel plates include: tension test, Charpy V-Notch impact test, drop weight test, high-temperature tension test, ultrasonic examination, magnetic particles examination.
