Product Description
A203 pressure vessel steel plate adopts nickel alloy steel material in the manufacture of high temperature pressure vessels. The performance of ASTM A203 boiler vessel plates is based on their Ni composition. ASTM A203 boiler container plates are available in five grades: Grade A, Grade B, Grade D, Grade E, and Grade F. ASTM A203 b oiler c ontainer p lates for g rade 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.
