EN 10025-6 S460QL1 is a premium, quenched and tempered steel plate that offers an outstanding combination of high strength (460 MPa min yield), exceptional low-temperature toughness (-60°C), and good weldability. It is the preferred material for designing structures and machinery that are lightweight, durable, safe, and capable of withstanding extreme loads and harsh environments.

S460QL1 High-strength Steel Plate significantly outperforms comparable steel grades in low-temperature toughness at -60°C and through-thickness performance, making it particularly suitable for critical load-bearing structures in extreme environments.

Specifications for exported EN 10025-6 S460QL1 High-strength Steel Plate:Thickness: 3 - 100 mm, Width: 1500 - 2500 mm, Length: 3000 - 12000 mm. 

Other specifications can be customized for cutting.

* EN 10025-6 S460QL1 High-strength Steel Plate allows for minor variations in the chemical composition of certain elements depending on the thickness.

Carbon Equivalent of S460QL1 High-strength Steel Plate

* The carbon equivalent value varies depending on the thickness. The greater the thickness of the steel plate, the higher the upper limit of the allowable carbon equivalent value (CEV).

* Carbon equivalent (CEV) calculation formula (IIW): CEV = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15

* The strength of S460QL1 High-strength Steel Plate slightly decreases as the thickness increases.

EN 10025-6 S460QL1 high-strength steel plate is widely used in the following fields due to its high strength, low-temperature toughness, and resistance to lamellar tearing:

1. Large engineering machinery: booms of cranes, chassis structures of excavators.

2. Bridges and buildings: load-bearing components of long-span bridges, steel structural frames of high-rise buildings.

3. Pressure vessels and storage tanks: pressure tanks for low-temperature environments, shells of large storage tanks.

4. Wind power and marine engineering: key sections of wind turbine towers, structural components of offshore platforms.

Comparison of Similar Grades

* The differences between S460Q, S460QL, and S460QL1 mainly lie in the impact temperature requirements.

Equivalent Standard Replacement Solution

* Grade equivalences are only approximate, actual mechanical properties and chemical composition should be compared.
