EN 10025-6 S890QL1 Steel Plates - Knowledge

S890QL1 is a European-standard, ultra-high-strength, fine-grained structural steel (EN 10025-6) that's quenched and tempered, offering a minimum yield strength of 890 MPa and excellent toughness, especially at low temperatures (down to -60°C), making it ideal for heavily loaded structures like cranes, heavy machinery, and vehicles. The "S" means structural, "890" is the yield strength, "Q" signifies quenching, and "L1" denotes specific low-temperature impact energy requirements.

Key Characteristics:

High Strength: Delivers superior durability with a minimum yield strength of 890 MPa.

Toughness: Features high impact toughness, even at very cold temperatures (e.g., 30 Joules at -60°C).

Weldability: Can be welded effectively, though preheating might be needed for thicker sections or cold conditions to prevent cracks.

Fine-Grained: Processed to have a fine grain structure for enhanced toughness.

Nominal thickness =< 50(mm) CEV max = 0.72
Depending on the thickness of the product and the manufacturing conditions, the manufacturer may add to the steel one or several alloying elements up to the maximum values given in order to obtain the specified properties
Nb, Ti, V, Zr: There shall be at least 0.015% of a grain-refining element present. AL is also one of these elements. The minimum content of 0.015% applies to soluble aluminium, this value is regarded as attained if the total aluminium content is at least 0.018%; in case of dispute the soluble aluminium content shall be determined

What is the difference between s890ql1 and s890ql?

he main difference between S890QL and S890QL1 is the specified minimum impact energy requirement at low temperatures: S890QL requires good impact toughness at -40°C, while S890QL1 offers superior toughness, guaranteeing the minimum impact energy at a colder temperature of -60°C, making it better suited for extremely cold conditions. Both are ultra-high-strength, quenched and tempered structural steels (EN 10025-6) with a minimum yield strength of 890 MPa, but the 'L1' designation signifies enhanced cold-weather performance.
