ASTM A299 material is a manganese-silicon carbon steel plate for use in welder boilers and other pressure vessels. ASTM A299 pressure vessel plates under this specification are produced in two grades. The steel shall be killed and shall conform to the fine austenitic grain size requirement. Tension test shall be made to conform to the requirements. There are two grades A299 Grade A, andA299年级B.根据ASTM A299规范。
Thickness: 3-150mm
Width: 1220-4200mm
Length: 5000-18000mm
