A516 steel plate is the most popular pressure vessel quality steel plate. Though it comes in different grades, A516-70 is the most common. It is suitable for use in moderate and lower temperature applications and where notch toughness is important. It offers an excellent combination of strength, notch toughness, and weldability.

There are four grades of this steel: 55, 60, 65, 70. 70 is the most widely used pressure vessel quality carbon steel plate. Tensile strength is one of the primary differences between grades. Grade 70 has a tensile strength between 485 -625 MPa, which is the highest of all the grades.
