| Property | Requirement | Note |
| Tensile Strength, min | 71 ksi (490 MPa) | |
| Yield Strength (0.2% offset), min | 31 ksi (220 MPa) | |
| Elongation in 2 in. (50 mm), min | 35% | For plates ≤ 3/4 in. (19 mm) thick. Slightly lower for thicker plates. |
| Hardness, max | 90 HRB (Rockwell B) | Typical Brinell Hardness (HBW) is ~180. |
| Important Fabrication Note: To achieve these mechanical properties and optimal corrosion resistance, the material and any welded fabrications must be supplied in the solution-annealed condition. This involves heating to a suitable temperature (e.g., 1100-1150°C) and rapidly quenching. | ||
