ASTM A299 Gr.B 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.B plates thickness over 1 inch [25mm].
ASTM A299 Gr.B Pressure Vessel Plates Size:
Thickness: 3-150mm
Width: 1220-4200mm
Length: 5000-18000mm
Coils available: 1.2 to 25mm
