A204 Pressure Vessel Steel Plate description

ASTM A204 boiler vessel plate is categorized into three grades: A, B, C based on the molybdenum content. The thickness of ASTM A204 boiler vessel plates is determined by the ability of the chemical composition to meet the specified mechanical property requirements. These plates find extensive use in various industries including petroleum, chemical, power generation, and boiler sectors, particularly in the manufacturing of reactors, heat exchangers, separators, spherical tanks, liquefied gas storage, nuclear reactor pressure vessels, boiler drum steam, liquefied petroleum gas facilities, hydropower stations, and high-pressure pipelines.
