S690QL / Equivalents
Is it really S690QL? 1 “equivalents” checked
Cross-reference tables pair grades by name and history. Here each pairing is judged on the minimum values each standard guarantees, with the sources for both sides.
Same strength class; guaranteed values agree within a few MPa. Still check thickness bands and impact quality.
A514 Grade QASTM
Same class of steel, but at least one guaranteed value is lower or tested differently. Recheck the design.
Commonly listed as an equivalent, but the guaranteed values do not support substitution.
Side by side
| Grade | Standard | Min. yield at 10 mm | Tensile at 10 mm | Match | What differs |
|---|---|---|---|---|---|
| S690QL |  EN 10025-6 | ≥ 690MPa1 | 770–940MPa1 | — | Reference grade. |
| A514 Grade Q | ASTM A514/A514M | ≥ 690MPa1 | 760–895MPa1 | Close match | Same 690 MPa (100 ksi) minimum up to 2.5 in, but A514 has no standard impact test and its 90 ksi step comes at 63.5 mm, not 50 mm. |
