A387 Chrome Moly Plate
ASME SA / ASTM A387 Gr 12, Gr 11, Gr 22, Gr 22L, Gr 21L, Gr 5, Gr 9, Gr 91
SA387 and A387 is the standard for chrome molybdenum pressure vessel alloy steel plates.
Applied Alloys stocks an extensive range of ASTM A387 plates in a variety of grades. Ready for immediate shipping. Plate can be cut to size or shape required. Ready for immediate shipping.
Chrome molybdenum increases the materials temperature tensile strength making it an excellent choice for elevated temperature environments. A387 displays excellent corrosion resistant and weldability making it ideal for the fabrication of pressure vessels and industrial boilers in the petrochemical and oil industry.
