ASTM A202 GR.A pressure steel plate is chromium-manganese-silicon alloy steel plates, intended particularly for welded boilers and other pressure vessels. ASTM A202 GR.A boiler plate is widely used in petroleum, chemical industry, power plant, boiler, etc, and used to make the reactor, heat exchanger, separator, spherical tank, gas cylinder, liquid tank, nuclear power reactors island, boiler drum, liquefied petroleum gas cylinders, high pressure water pipes, turbine hydropower station equipment and components such as spiral case.
