Steel standard ASTM A204/A204M Gr.A for pressure vessel steel plates
ASTM A204 Grade A steel shall be supplied normally in the as-rolled delivery condition.The plates also may be ordered in Normalised or stress relieved or both.For thickness above 40mm,pressure vessel steel plate SA204 Grade A shall be in Normalised heat treatment.
ASTM A204/A204M Gr.A for pressure vessel steel specification covers molybdenum alloy, intended particularly of welded boilers and others pressure vessels steel plate in A204 Gr. A, A204 Gr .B and A 204 Gr .C.
ASTM A204 Gr.A for pressure vessel steel plate is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator, spherical tank, liquefied gas, nuclear reactor pressure vessel, boiler steam drum steam, liquefied petroleum, hydropower station, high pressure pipe.
