ASTM A516 carbon steel is same as A516 pressure vessel steel under ASTM A516/A516M technical standard. More correctly, it is A516 vessel steel or A516 boiler steel, as the ASTM A516 steel is mainly for pressure vessels and boilers use. But some habitually call it ASTM A516 carbon steel. It is just the same thing.
ASTM A516 carbon steel covers 4 grades: A516 grade 55, A516 grade 60, A516 grade 65, A516 grade 70.The 4 ASTM A516 carbon steel grades are mainly defined by their different tensile and yield strength range, which is influenced by content of carbon. For example, A516 grade 70 carbon steel has the highest tensile and yield strength range due to the highest carbon content.
