Pressure Vessel Plate of ASTM A299 is manganese-silicon carbon steel plate for use in welded boilers and other pressure vessels. Plate is available in two grades having strength levels: Grade A, Grade B. The specified minimum yied strength decreases for thicknesses over 1 in.(25mm).
The maximum thickness of plate is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice nomally limits the maximum thickness of plates furnished under this specification to 8 in. (200mm).
Steel Plates of ASTM A299 widely used in pressure vessels and boiler equipments.
