ASTM A299 Gr.A 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: A299 Gr.A and A299 Gr.B. The specified minimum yield strength decreases for A299 Gr.A plates thickness over 1 inch [25mm].
