What is ASTM A204?
ASTM A204 specification covers molybdenum alloy steel plates, intended particularly for welded boilers and other pressure vessels. Plates under this specification are available in three grades having different strength levels: Grade A; Grade B; and Grade C.
What is the composition of ASTM A204 Grade B?
ASTM A204 Grade B is a boiler quality grade of steel. The Astm A204 Grade B Plate is designed with a superior composition of carbon, molybdenum, manganese sulfur, phosphorus, and silicon. The content embedded in these plates gives them enhanced resistance to corrosive and reducing media.
