ASTM A514 Grade H is a high-strength, quenched and tempered alloy steel with the following properties:
| Property | Value |
|---|---|
| Yield Strength (min) | 100 ksi (690 MPa) |
| Tensile Strength | 110-130 ksi (760-895 MPa) |
| Elongation in 2″ (min) | 16% |
| Hardness | 235-293 HBW |
ASTM A514 Grade H steel is commonly used in:
ASTM A514 Grade H is produced through quenching and tempering processes. Available dimensions include:
| Thickness (in/mm) | Width (in/mm) | Length (in/mm) |
|---|---|---|
| 1.251 – 2.00 | 72 – 120 | 240 – 600 |
| 31.78 – 50.8 | 1800 – 3050 | 6100 – 15200 |
ASTM A514 Grade H has good weldability but requires careful attention to welding procedures. Proper preheat and interpass temperatures should be maintained to prevent cracking. Shear burrs and heat-affected zones of thermal cut edges should be removed by grinding prior to cold forming.
| Grade | Thickness Range (in) | Yield Strength (min ksi) |
|---|---|---|
| H | 1.251 – 2.00 | 100 |
| B | 0.188 – 1.250 | 100 |
| E | 0.185 – 6.00 | 100 (up to 2.5″), 90 (2.5-6″) |
| F | 0.185 – 2.50 | 100 |
While ASTM A514 Grade H has a higher initial cost, its high strength allows for thinner sections and reduced overall weight in structures. This can lead to cost savings in material usage, transportation, and installation, particularly in large-scale projects.
