Product Description
ASME SA387 and ASTM A387 Gr. 11/12/22 Boiler and Pressure Vessel Steel Sheet Plate
ASME SA387 and ASTM A387 Chrome Moly Plate for Boiler Applications
The most commonly used steel specifications for Chrome Moly plate are ASME SA387 and ASTM A387. These specifications provide chromium-molybdenum alloy steel plates designed for pressure vessel applications in boilers and other high-temperature service environments.
  • Chemical and mechanical properties of the ASME and ASTM specifications are identical
  • Available from stock with optional cutting to size and shape as required by customer specifications
  • SA387 and A387 are standardized specifications for pressure vessel plates, alloy steel, chromium-molybdenum
