A387 Grade 21 Class 2

A387 Grade 21 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 3% and the Mo content 1%.

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 21 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.
