ASTM A516 Gr 70 VS A36, ASTM A516 steel and A36 steel actually belong to different steel types. ASTM A516 steel is pressure vessel and boiler steel. ASTM A36 steel is mild steel. For the chemical content of carbon, ASTM A516 steel and A36 steel are also called carbon steel. But their properties have obvious difference.

ASTM A516 Gr 70 VS A36 carbon steel plate in application:
ASTM A36 carbon steel plate is used in heavy machinery, industrial boilers, wagon tippers, feeders, stackers, crushers, loaders, cranes, shipping industry and supporting frames for equipment used in metallurgical and other heavy industries.
ASTM A516 Gr 70 steel plate is mainly used for pressure vessel and boiler, oil and gas as well as petrochemical industries.
The main ASTM carbon steel plates and pressure vessel steel plates standards BBN steel conduct are:
ASTM carbon steel plates: A36, A283, A572, A573 and so on.
ASTM pressure vessel steel plates: A202, A203, A204, A285, A299, A302, A387, A515, A516, A517, A533, A537, A612, A662, A841, etc.
