Pressure Vessel Plate of ASTM A387 is chrominum-molybdenum alloy steel intended primarily for welded boilers and pressure vessels designed for elevated temperature service. Plate are available in several grades having different alloy cintents: Grade 5, Grade 9, Grade 11, Grade 12, Grade 22, Grade 91.... Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels as defined in Tensile Requirement table. Grades 21L and 22L are available only as Class 1. Grade 91 is available only as Class 2.
The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirement.
