Product Description

ASTM SA204 GrA,B,C Boiler and Pressure Vessel Steel Plate

Standard, Grades & Thicknesses

Pressure vessel plates made of ASTM A204 (identical with ASME SA-204) steels are typical molybdenum-alloy steel plates intended particularly for welded boilers and other pressure vessels. The steel grades covered by ASTM A204/ ASME SA-204 are all carbon-molybdenum alloy steels with nominal composition of C-0.5Mo. Plates under this standard specification are available in three grades having different strength levels as follows:

Grade	Tensile Strength ksi [MPa]
A	65-85 [450-585]
B	70-90 [485-620]
C	75-95 [515-655]

The maximum thickness of ASTM A204 plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thicknesses of plates made of Grade A, Grade B and Grade C steel to 6″ [150 mm], 6″ [150 mm], 4″ [100 mm], respectively.
