A387 Grade 12 Class 2 is a chromium molybdenum alloy steel plates intended primarily for welded boiler and pressure vessels designed of elevated temperature service. The Cr content 1% and the Mo content 0.5%.
Each grade except grade 21L,Grade 22L,Grade
91 and Grade 911 is available in two classes of tensile strength levels. Grade
91 and Grade 911 are available only as Class 2.
A387 Grade 12 Class 2 max thickness of
plates is limited only by the capacity of the composition to meet specified
mechanical property requirements.
Gangsteel is a large agent in HBIS and cooperated with Wuyang Iron and steel co.,ltd to export high quality and super thickness steel plate.
