low alloy a387 grade 11class1or class 2 steel plate
1.what is the a387 gade 11 plate
ASTM A387 Gr 11 CL 2 is a chromium molybdenum alloy steel plate intended primarily for welded boiler and pressure vessels designed of elevated temperature service. The Cr content 1.25% 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.we are exporter of astm a387 grade 11 class 2 plate in india
