General requirements for delivery
Material shall conform to the requirements of ASTM A 20.
This grade must be killed and made to a fine grain practice. Plates over 1-1/2 thick must be normalized. Additionally, when impact (notch toughness) tests are required on plates up to 1-1/2 thick, the plates must be normalized.
This specification covers carbon steel plates intended primarily for use in welded pressure vessels where improved notch toughness is important. It allows for four different strength levels. The most common is Grade 70.
