ASTM A204 alloy steel sheet A204 Gr B boiler grade pressure vessel steel plate
Based on it’s Mo composition, A204 alloy steel sheet cover 3 grades: A, B, C. The maximum plate thickness is limited only by the chemical composition to achieve certain mechanical property figure; steel plate and coils under this specification normally limit thickness as follows: ASTM A204 grade A: 6 in[150mm]; ASTM A204 grade B: 6 in[150mm]; ASTM A204 grade C: 4 in[100mm]
