Accreditation Administration System:
This specification ASTM A204/A204M covers molybdenum_alloy steel plates, intended primarily for welded
boilers and other pressure vessels,including such grades:ASTM A204GrA,A204GrB,A204GrC.The same in
standard ASME, including ASME SA204GrA, SA204GrB, SA204GrC.Generally Grade A204GrC is the most
common,now we give you the property analysis in the following table:
