EN 10025-6 S500QL is a high-strength quenched and tempered structural steel plate under the European Standard (EN) system. Its core characteristics include high strength and excellent low-temperature toughness, making it widely used for structural components in cold and heavy-duty environments. It is a common material in fields such as construction machinery, bridges, and marine engineering.

* The chemical composition of EN 10025-6 S500QL High Strength Steel Plate is adjusted within a certain range depending on the thickness.

Carbon Equivalent of S500Q 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 S500QL high-strength steel plates. For detailed information, please contact us for inquiries.

* The strength of S500Q high-strength steel plate slightly decreases as the thickness increases.

The combination of "high strength + low-temperature toughness" in EN 10025 S500QL high-strength steel plates makes them suitable for structural applications with high loads and harsh environments, primarily including:

1. Construction Machinery: Crane arm frames, excavator buckets/booms, loader chassis, etc. (requiring weight reduction and impact resistance);

2. Mining Machinery: Dump truck bodies, crusher frames (withstanding heavy loads and material impact);

3. Bridge and Building Steel Structures: Load-bearing components of long-span bridges in cold regions (e.g., Northern Europe, Northeast China), core columns of super high-rise steel structures (resisting low-temperature wind loads);

4. Marine Engineering: Offshore platform structural components, flange connections for offshore wind turbine towers (resisting low-temperature marine environments and corrosion fatigue, requiring anti-corrosion treatment);

5. Special Vehicles: Heavy-duty truck frames, tanker truck bodies (lightweight requirements + road impact resistance);

6. Pressure Vessels and Energy Storage Equipment: Support structures for high-pressure hydrogen storage tanks and cryogenic tanks (requiring high strength and low-temperature safety).

The Differences Between Grades Within The Same Series

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