EN10025 S690QL High Yield Structural Steel Properties

S690QL carbon steel is a High Yield Structural Steel grade which has been produced for its outstanding tensile strength properties and durability. Its yield strength is usually 690 MPa and its ultimate tensile strength increases up to 980 MPa. S690QL structural steel is considered an ideal choice for applications where high strength is required and no other steel grade can work well instead. As a HYSD steel grade, it offers higher strength and better weldability than conventional steels of similar strength. the most common size available for S690QL is plate thickness between 6 mm and 300 mm. Some of the bigger size plates can go up to 1250 mm and a width of up to 3000 mm. In terms of length, S690QL is commonly available in cut lengths between 2 m and 12 m.

When it comes to its physical properties, S690QL high-strength steel with a smooth surface finish and excellent corrosion resistance. When exposed to extreme temperatures or moisture, it has good performance in resisting short-term oxidation and is self-protecting against rust in most cases. Its strength and durability mean that it is often used for heavy engineering projects and other large construction projects.

One of the biggest advantages of S690QL High Yield Structural Steel is its excellent fatigue resistance. Its high tensile strength and impact resistance make it perfect for applications where vibration and shock resistance is required. This makes it a great choice for hydraulic tubing, spring manufacturing, and other high-stress applications.

Some of the key properties of S690QL are as follows:
Yield Strength: 690 MPa
Tensile Strength: 980 MPa
Elongation: 16%
Density: 7.85 g/cm3
Temperature: -20℃ ~ +300℃

S690QL carbon structural steel is a strong, resilient, and cost-effective steel grade that can be used in a variety of applications, from heavy-duty engineering projects to production of high-strength components. Its durability and reliable performance make it an excellent choice for most tasks.
