ASTM A514 Grade Q is a high-strength, quenched and tempered alloy steel with the following properties:
| Property | Value |
|---|---|
| Yield Strength (min) | 690 MPa (100 ksi) for thickness up to 63.5 mm |
| Tensile Strength | 760-895 MPa (110-130 ksi) |
| Elongation in 2″ (min) | 16% for thickness up to 63.5 mm |
| Hardness | 235-293 HBW (for thickness up to 19 mm) |
ASTM A514 Grade Q steel is commonly used in:
ASTM A514 Grade Q is produced through quenching and tempering processes. Available dimensions include:
| Thickness (in/mm) | Width (in/mm) | Length (in/mm) |
|---|---|---|
| 0.185 – 6.00 | 60 – 131.9 | 73 – 590 |
| 4.70 – 152 | 1500 – 3350 | 1900 – 15000 |
ASTM A514 Grade Q has good weldability but requires careful attention to welding procedures. Proper preheat and interpass temperatures should be maintained to prevent cracking.
Grade Q offers similar yield and tensile strengths to other A514 grades, but is available in a wider range of thicknesses compared to some grades.
While ASTM A514 Grade Q has a higher initial cost, its high strength allows for thinner sections and reduced overall weight in structures, potentially leading to cost savings in material usage, transportation, and installation.
