A204 Pressure Vessel Steel Plate
A204/SA-204 steel is a carbon molybdenum alloy steel with a nominal composition of C-0.5Mo. According to this standard specification, steel plates can be divided into three different strength grades: Grade A, Grade B and grade C.

PRODUCT  INFORMATION

The maximum thickness of ASTM A204 plates is limited only by the composition’s ability to meet the specified mechanical property requirements. However, current practice normally limits the maximum thickness of plates made of Grade A, Grade B, and Grade C steel to 6′′ [150 mm], 4′′ [100 mm], respectively. Plates under 1-1/2″ [40 mm] in thickness must be supplied in the as-rolled condition. Plates over 1-1/2″ [40 mm] in thickness may be normalized or stress relieved, or both.
