ASTM A299 specification covers manganese-silicon carbon steel plates for use in welded boilers and other pressure vessels. Plates under this specification are produced in two grades (A, B). Yield and tensile strength of Gr. B is higher than Gr. A. Due to high composition of C, Mn, Si. ASTM A299 is widely used for manufacturing pressure and boiler equipments.
