product description

A203 Pressure Vessel Steel Plate Description

ASTM A203 boiler container plates are available in five grades: Grade A, Grade B, Grade D, Grade E, and Grade F. ASTM A203 boiler container plates for grade A, B, D and E shall be normalized as required. The chemical composition shall conform to the requirements of ASTM A203/A203M. At the same time, ASTM A203 boiler container plate needs to do two mechanical properties test: namely tensile test and impact test. ASTM A203 boiler vessel plate is widely used in petroleum, chemical industry, power station, boiler and other industries, for the manufacture of reactor, heat exchanger, separator, spherical tank, oil and gas tank, high pressure pipeline, water turbine and other equipment and components.
