S690 QL is a top-grade structural steel that comes with high yield produced in compliance with EN 10025:6:2004. This type of steel has impressive bending and welding properties, making it an excellent choice for structures that require complex shapes and designs.
One of the most significant advantages of S690 steel is its exceptional strength-to-self-weight ratio. It means that it is highly efficient for use in heavily loaded structures that require robust materials to handle weight and pressure with ease. It also offers a better strength level than traditional carbon steel grades, with a minimum yield of 690MPa.
S690 further offers impressive forming and welding qualities that make it the perfect steel choice for complex structures and heavy-duty equipment. Its outstanding strength level and welding properties make it suitable for use in the construction industry, heavy machinery, and transportation equipment, among other applications.

The S690Q steel has the following 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 commonly employed in the construction of structures that are exposed to extremely heavy loads. These include mining and heavy-construction equipment, crane equipment, offshore drilling platforms, supporting structures for wind turbines, bridges, and trestles.
Given its ability to withstand the rigors of heavy loads, S690Q steel is in high demand in various industries. In the mining sector, it is primarily used in the construction of heavy-duty equipment designed to extract raw materials from the earth. Meanwhile, crane equipment typically relies on this type of steel for the construction of the structure that supports the crane.
Offshore drilling platforms are another common application of S690Q steel. These platforms are typically located in harsh environments, such as deep ocean waters, and must be built to withstand high winds, waves, and other extreme conditions. Similarly, supporting structures for wind turbines require a steel that can withstand the constant stresses of rotating machinery and high wind speeds.
Bridges and trestles require a strong material that can support the weight of heavy vehicles and other loads. S690Q steel meets this need, often being used to construct the support structures of these large-scale infrastructure projects. Whether in mining, construction, or renewable energy, S690Q steel has proven to be a reliable and durable material for applications that require extreme resilience and strength.
