ASTM A204 Grade B Steel Plates, A204 Grade B Low Alloy Steel Plates, A204 Grade B Molybednum Steel Plates, A204 Grade A, B, C, A204 Pressure Vessel Steel Plates 
Supplier ASTM A204 specification covers molybdenum alloy steel plates, intended particularly for welded boilers and other pressure vessels. Plates under this specification are available in three grades having different strength levels: Grade A; Grade B; and Grade C. The steel shall be killed. The steel shall conform to the chemical requirements specified. Tension tests on plates shall conform to the requirements specified.

Mo-Alloy steel plate SA204 Grade A,SA204 Grade B, SA204 Grade C, A204 Grade A, A204 Grade B,A204 Grade C which are under steel specification ASME SA204 / SA204M and ASTM A204 / A204M.All these steel grades are normally used for pressure vessel steel plates,for A204 Grade A and SA204 Grade A pressure vessel steel plate,the minimum yield strength is 255 Mpa,tensile strength within 450-585 Mpa, for pressure vessel steel plate A204 Grade B and SA204 Grade B,the minimum yield strength is 275 Mpa,tensile strength within 485-620 Mpa,for boiler steel plate A204 Grade C and SA204 Grade C,yield strength shall be above 295 Mpa,tensile strength from 515 Mpa to 655 Mpa.

This specification covers molybdenum-alloy steel plates, intended particularly for welded boilers and other pressure vessels.

Plates under this 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 plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thickness of plates furnished under this specification as follows:

Grade Maximum Thickness, in. [mm]
A204 A 6 [150]
A204 B 6 [150]
A204 C 4 [100]
