A36 PLATES - MECHANICAL PROPERTIES |
|
|---|---|
| Property | Value |
| Tensile, ksi | 58 - 80 |
| Yield, ksi min | 36 |
| Elongation % min in 2" | 23 |
| Elongation % min in 8" | 20 |
Notes:
- For plates wider than 24", the elongation requirement is reduced by two percentage points.
- Yield point is 32 ksi for plates over 8" in thickness.
- Elongation is not required to be determined for floor plates.
