ASTM A299 Carbon Steel for Pressure Vessel

ASTM A299 Carbon Steel for Pressure Vessel

ASTM A299 steel(ASME SA299 ) is a kind of manganese-silicon carbon steel plates for use in welded boilers and other pressure vessels. Plates under this specification are produced in two grades: A299 Grade A, A299 Grade B.

ASTM A299 steel(ASME SA299 ) is a kind of manganese-silicon carbon steel plates for use in welded boilers and other pressure vessels. Plates under this specification are produced in two grades: A299 Grade A, A299 Grade B. Yield and tensile strength of Grade B is higher than Grade A. ASTM A299 plate is used in fabricators serving industry, especially in the oil, gas and chemical supply markets.
Due to high composition of C, Mn, Si. ASTM A299 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.
