Accreditation Administration System:
ASTM A387Gr11CL2, ASME SA387Gr11CL2 steel plate which contains chromium_molybdenum alloy
intended primarily for welded boilers and pressure vessels designed for elevated temperature service.
Generally these grades are rolled under HIC Test (including Aand B solutions).Now we named it as
A387Gr11CL2 +HIC or A387Gr11CL2(HIC).Other relative grades in this specification as list:
ASTMA387Gr11CL1|A387Gr11CL2|A387Gr12CL1|A387Gr12CL2|A387Gr22CL1|A387Gr22CL2|
A387Gr5CL1|A387Gr5CL2
Now we give you our rolling values about A387Gr11CL2 as follows:
