Product Description

A203 pressure vessel steel coil employs nickel alloy steel material in the manufacture of high temperature pressure vessels. The performance of ASTM A203 boiler vessel coil is based on their Ni composition. A203 boiler container coils are available in five grades: Grade A, Grade B, Grade D, Grade E, and Grade F. The chemical composition shall conform to the requirements of ASTM A203/A203M. At the same time, ASTM A203 boiler container coil is subject to two mechanical properties test: namely tensile test and impact test after production . This kind of coil 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.
