ASTM A662 Grade A steel material belong to standard
ASTM A662/A662M, which covers three grades of carbon manganese-silicon steel plates intended primarily for welded pressure vessels in service where improved lower temperature notch toughness is important.
ASTM A662 Grade A steel plates maximum thickness is limited by the capacity of the composition to meet the specified mechanical property requirements.
