S690 QL is a structural steel grade known for its high yield strength. It has been produced in compliance with EN 10025:6:2004, ensuring that it meets the required standards for quality and safety.
One of the notable features of S690 steel is its excellent strength-to-weight ratio. This means that it is highly efficient for use in structures that are subject to heavy loads, delivering superior strength while minimizing weight.
Compared to standard carbon steel grades, S690 offers a higher level of strength with a yield of minimum 690MPa. This makes it an ideal choice for applications where added strength is required.
S690 also boasts good forming and welding properties. This means that it can be easily shaped and fabricated according to specific requirements, without compromising its high performance capability.
Based on the specification EN 10025-6, S690Q steel has the following chemical composition:
| C | Si | Mn | P | S | N | B | Cr | Cu | Mo | Nb | Ni | Ti | V | Zr |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 0.20 | 0.80 | 1.70 | 0.025 | 0.015 | 0.015 | 0.005 | 1.50 | 0.50 | 0.70 | 0.06 | 2.0 | 0.05 | 0.12 | 0.15 |
Moreover, S690Q steel also has specific mechanical properties:
| Nominal gauge, mm | Minimum yield strength, ReH (MPa) | Ultimate tensile strength, Rm (MPa) | Minimum elongation ratio σ, % | Brinell hardness number, HB (MPa) |
|---|---|---|---|---|
| >3 ≤ 50 | 690 | 770-940 | 14 | 228-278 |
| >50 ≤ 100 | 650 | 760-930 | 14 | 225-276 |
| >100 ≤ 150 | 630 | 710-900 | 14 | 210-266 |
S690Q steel is a high-strength structural steel that is specifically designed to withstand extreme loads. It is commonly used in various applications, including mining and heavy-construction equipment, crane equipment, offshore drilling platforms, supporting structures for wind turbines, bridges, and trestles.
The steel's superior strength and toughness make it an excellent choice for structures that must withstand high stress and heavy impact. In the mining industry, for example, S690Q steel is often used in the fabrication of haul trucks, which must endure the harsh, abrasive conditions of mining operations.
Similarly, in the construction industry, S690Q steel can be found in the frames and booms of heavy-duty cranes, as well as in the supports for large-scale bridge and trestle systems. Offshore drilling platforms also rely on the durability and strength of S690Q steel to withstand the unpredictable conditions of the open sea.
Overall, S690Q steel is a versatile and reliable material that plays an important role in many challenging engineering projects. Its ability to withstand extreme loads and harsh environments make it an essential component in a variety of heavy-duty structures and equipment.
