ASTM A662 standard specification for pressure vessel plates, carbon-manganese-silicon steel, for moderate and lower temperature service.
ASTM A662, as a kind of low alloy steel, chemical composition difference of the 3 steel grades is mainly for Mn element, increasing of Mn content in steel plate will improve yield and tensile strength character.

ASTM A662 plates over 40mm in thickness shall be normalized. Plates of Grades B and C, 40 mm and under in thickness, are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.
