Product Description

ASTM A204 boiler vessel plate is molybdenum alloy steel plate, mainly suitable for welding boilers and high temperature pressure vessels. According to the molybdenum content, ASTM A204 boiler vessel plate is divided into 3 grades: A, B, C. The thickness of ASTM A204 boiler vessel plates is limited only by the ability of the chemical composition to meet the specified mechanical property requirements. ASTM A204 boiler vessel plate s are widely used in petroleum, chemical industry, power station, boiler and other industries, particularly in the manufacture of reactors, heat exchangers, separators, spherical tanks, liquefied gas, nuclear reactor pressure vessels, boiler drum steam, liquefied petroleum gas, hydropower stations, high pressure pipelines, etc.
