A500 Gr A, B & C Tubing Specification
Below are the physical properties required to meet the three grades that we produce ASTM A500 square, rectangle and specially shaped tubing. A flattening test is not required for non-round tubing produced to A500.
| Grade | Yield (min) | Tensile (min) | Elongation (min) |
| Grade A | 39,000 psi | 45,000 psi | Determined by wall |
| Grade B | 46,000 psi | 58,000 psi | Determined by wall |
| Grade C | 50,000 psi | 62,000 psi | Determined by wall |
Round Tubing
Below are the physical properties required to meet the three grades that we produce ASTM A500 round tubing. A flattening test is also a standard requirement for round tubing produced to the A500 specification.
| Grade | Yield(min) | Tensile (min) | Elongation (min) |
| Grade A | 33,000 psi | 45,000 psi | Determined by wall |
| Grade B | 42,000 psi | 58,000 psi | Determined by wall |
| Grade C | 46,000 psi | 62,000 psi | Determined by wall |
