ASTM A516 Carbon Steel for Pressure Vessels
ASTM A516 steel (or ASME SA516 steel) is a carbon steel plate grade utilized
primarily in welded pressure vessels for moderate to lower
temperature service. This material is produced in grades 55, 60, 65
and 70. This material is also offered in the normalized condition
where improved notch toughness is required.
This specification of ASTM A516 covers carbon steel plates intended
primarily for service in welded pressure vessels where improved
notch toughness is important. According to different strength
levels, the plates are available in four grades: Grades 55, 60, 65,
and 70. The most common is Grade 70 or called out A516 Grade 70 steel. The maximum thickness of plates is limited only by the capacity
of the composition to meet the specified mechanical property
requirements. The steel shall be killed and shall conform to fine
austenitic grain size requirements. The mechanical properties such
as tensile strength, yield strength, and elongation shall be
determined by a tension test for the plates.
