S890QL vs S960QL
These two grades are listed as equivalents of each other: their chemistry windows overlap and they serve the same applications. They are not always identical — check the differences below before substituting, especially in certified designs.
S890QL
Structural & HSLA Steel
S890QL is the EN 10025-6 Q&T structural plate with 890 MPa minimum yield — a step beyond S690QL for boom and chassis designs where every kilogram of dead weight costs payload. It uses the same lean ladle chemistry envelope as the whole S460–S960 family; strength comes from the quench-and-temper practice.
Standards: DIN S890QL (EN 10025-6) · GB Q890 (GB/T 16270, near)
S960QL
Structural & HSLA Steel
S960QL is the strongest grade in the EN 10025-6 structural family: 960 MPa minimum yield with −40 °C toughness, for the most weight-critical booms and lifting structures. Availability is thinner and lead times longer than S690QL/S890QL, and fabrication discipline is unforgiving.
