Products Description
S890QL1 is a high-strength quenched and tempered structural steel grade specified under EN 10025-6. It is engineered for applications that require superior load-bearing capacity, excellent weldability, and good toughness even at low temperatures.
The designation "QL1" indicates that the steel provides impact toughness tested at -60°C, offering enhanced performance in cold climates and demanding structural environments.
With a minimum yield strength of 890 MPa and a tensile strength ranging from 940 to 1100 MPa, S890QL1 steel allows for the design of lighter, more efficient structures without compromising safety.
Its elongation (A5) of 12–15% and Charpy V-notch impact value of ≥30 J at -60°C ensure a reliable balance between strength and ductility. This makes it ideal for bridge construction, heavy-duty cranes, offshore structures, mining equipment, and transport machinery.
