ASTM A204 boiler vessel coil is molybdenum alloy steel coil, mainly suitable for welding boiler and high temperature pressure vessel. According to the molybdenum content, ASTM A204 boiler vessel coil is divided into 3 grades: A, B and C. ASTM A204 The thickness of the boiler vessel coil is limited only by the ability of the chemical composition to meet the specified mechanical property requirements.
