Maximum Thickness Limited
The maximum thickness of the plates is restricted solely by the ability of the composition to meet the specified mechanical property requirements. For plates manufactured from coils and provided without heat treatment or only with stress relieving, the requirements and test results must comply with A20/A20M. Coils are not considered qualified under this specification until they are cut into plates.

a516 gr60 vs q345r
ASTM A516 Grade 60 and Q345R are both carbon steel plates used for pressure vessels and boilers, but they differ significantly in strength, controlling standards, and equivalent grades. Q345R is closer in strength to A516 Grade 70 than to A516 Grade 60.
Comparison of A516 Grade 60 and Q345R
| Feature | A516 Grade 60 | Q345R |
|---|---|---|
| Standard | ASTM/ASME | GB (Chinese National Standard) |
| Classification | Carbon steel plate for moderate and low-temperature service in pressure vessels. | Low-alloy, high-strength steel for pressure vessels. |
| Equivalent grade | Roughly equivalent to the Chinese grade Q245R. | Roughly equivalent to the American standard A516 Grade 70 due to similar tensile strength. |
| Yield strength (min) | ≥ 220 MPa (32 ksi) | ≥ 345 MPa (50 ksi) for thin plates. (Yield strength decreases with increasing thickness). |
| Tensile strength | 415–550 MPa (60–80 ksi) | 510–640 MPa (74–92 ksi) for thin plates. (Tensile strength range decreases slightly with increasing thickness). |
| Main alloying elements | Primarily carbon, with manganese and silicon. | Contains small amounts of manganese, silicon, niobium, vanadium, and titanium. |
| Weldability | Excellent weldability suitable for many fabrication methods. | Good weldability, but requires more control than A516 Gr 60 to avoid cracking due to higher strength and alloy content. |
| Toughness | Good notch toughness, especially for lower-temperature service. | Higher strength may slightly reduce toughness compared to A516 Gr 60, but it meets impact toughness requirements. |
| Applications | Pressure vessels, boilers, and industrial equipment for moderate and lower temperature service. | Pressure vessels, boilers, heat exchangers, and tanks for higher pressure and temperature services compared to lower-grade steel. |
Which steel is right for your project?
When choosing between A516 Grade 60 and Q345R, consider the specific needs of your application:
