1. Simple Description:

1) ASTM Standard A387/A387M-11 Chromium-Molybdenum Alloy Steel Sheets for Pressure Vessels Chemical Composition

Impact Temperature Delivery Condition Normalized + Tempered/Annealed.

2) Each grade excepi Grades 21L 22L and 9 is available intolasses of tensile srength 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 A1017/A1017M.

3) The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
