Product Description

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