Here is the Scope for SA 204;

1. Scope
1.1 This specification covers molybdenum-alloy steel
plates, intended particularly for welded boilers and other
pressure vessels.
1.2 Plates under this specification are available in three
grades having different strength levels as follows:
Tensile Strength,
Grade ksi [MPa]
A 65–85 [450–585]
B 70–90 [485–620]
C 75–95 [515–655]

You need to review the applicable specifications for pipe- SA 672 which contains rolled and seam welded SA 204 plate specification.

For flanges review ASME B16.5
and for fittings ASME B16.9 and 16.11
