ASTM A516 is a specification that covers carbon steel plates intended for service in welded pressure vessels at moderate and lower temperatures. The specification includes three grades: Grade 70, Grade 65, and Grade 60. Here are the specifications for each grade:
ASTM A516 Grade 70 (A516 GR 70):
Tensile Strength: 485-620 MPa (70-90 ksi)
Yield Strength: 260 MPa minimum (38 ksi)
Elongation: 17% minimum in 200 mm (8 inch), 21% minimum in 50 mm (2 inch)
Thickness: Up to 3 inches
ASTM A516 Grade 65 (A516 GR 65):
Tensile Strength: 450-585 MPa (65-85 ksi)
Yield Strength: 240 MPa minimum (35 ksi)
Elongation: 19% minimum in 200 mm (8 inch), 23% minimum in 50 mm (2 inch)
Thickness: Up to 3 inches
ASTM A516 Grade 60 (A516 GR 60):
Tensile Strength: 415-550 MPa (60-80 ksi)
Yield Strength: 220 MPa minimum (32 ksi)
Elongation: 21% minimum in 200 mm (8 inch), 25% minimum in 50 mm (2 inch)
Thickness: Up to 3 inches
These grades of ASTM A516 plates are widely used in various industries such as oil and gas, petrochemical, power generation, and shipbuilding due to their excellent weldability, notch toughness, and resistance to corrosive environments.
It's important to note that specific requirements may vary depending on the manufacturer and customer specifications. It is recommended to consult the relevant standards, engineering specifications, and material certification for precise and up-to-date information related to ASTM A516 steel plates.
