EN 10025-6 S500QL1 is a high-strength quenched and tempered structural steel under the European Standard (EN) system. The core characteristics of EN 10025-6 S500QL1 High Strength Steel Plate are high strength (yield strength ≥ 500 MPa) and excellent low-temperature toughness (impact energy tested at -60°C ≥ 30 J).

It is primarily used in load-bearing structural applications that require strict material strength and low-temperature toughness, such as engineering machinery, bridges, and offshore engineering.

* The chemical composition of EN 10025-6 S500QL1 High Strength Steel Plate is adjusted within a certain range depending on the thickness.

Carbon Equivalent of S500QL1 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

* Yuxin Steel has sufficient stock of EN 10025-6 S500QL1 high-strength steel plates. For detailed information, please contact us for inquiries.

* The strength of S500QL1 high strength steel plate slightly decreases as the thickness increases.

EN 10025 S500QL1 High Strength Steel Plate is primarily used in the following scenarios:

1. Engineering machinery: Structural components subjected to dynamic loads, such as crane booms, excavator arms, and loader frames.

2. Offshore engineering: Offshore platform columns, subsea pipeline support structures (resistant to low-temperature and corrosive seawater environments, requiring anti-corrosion treatment).

3. Bridges and buildings: Load-bearing beams for long-span bridges, core frames of high-rise steel structures (preferred for use in cold regions).

4. Heavy-duty vehicles: Mining truck bodies, special transport vehicle frames (designed to withstand heavy loads and bumpy impacts).

5. Pressure vessels: Shells for medium- and low-pressure pressure vessels (must meet strength and low-temperature safety requirements, such as liquefied natural gas tank accessories).

The Differences Between Grades Within The Same Series

* The differences between S500Q, S500QL, and S500QL1 mainly lie in the impact temperature requirements.

Equivalent Grades of EN 10025-6 S500QL1 High-strength Steel Plate

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