ASME SA299 Grade A is a manganese-silicon carbon steel plate for use in welder boilers and other pressure vessels. ASME SA299 carbon steel under this specification are produced in two grades: SA299 Gr.A and SA299 Gr.B. ASME SA299 Grade A steel is widely used for manufacturing pressure and boiler equipments. Plates of this standard under this thickness of 50 mm are normally supplied in as-rolled condition. Plates may be ordered normalized or stress relieved, or both. Plates over 50 mm in thickness shall be normalized.
