ASTM A662 standard applies to the carbon-manganese steel that have high requirements for welding pressure vessel with low-temperature notch toughness. The maximum thickness of the ASTM A662 Pressure Vessel Plate steel sheet is limited only by the ability of the chemical composition and it can meet the specified mechanical performance requirements. However, the maximum thickness of the steel sheet currently supplied is limited to 2 in. (50 mm).
