ASTM A 387/A 387M REV A Document Information:
Title
Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium- Molybdenum
ASTM International
Publication Date:
Oct 1, 2006
Scope:
This specification2 covers chromium-molybdenum alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature service.
Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels as defined in the Tensile Requirements tables. Grades 21L and 22L are available only as Class 1. Grade 91 is available only as Class 2.
NOTE 1—Grade 911, previously covered by this specification, is now covered by Specification A 1017/A 1017M.
The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents. Therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
2 For ASME Boiler and Pressure Vessel Code applications, see related Specifi- cation SA-387/SA-387M in Section II of that Code.
*A Summary of Changes section appears at the end of this standard.
