PRODUCT DETAILS
A204 Pressure Vessel Steel Plate 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 container 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.
