S690QL is the name of a high-strength steel grade. "S" steel is a standard designation for structural steels, and the number "690" refers to the minimum yield strength of the steel plate (690 MPa). "QL" stands for "high ductility".
S690QL steel is often used in applications such as machinery, cranes, construction machinery and shipbuilding operating under heavy loads. This steel grade has high strength, good impact resistance and good weldability.
In English, you can express it as steel grade S690QL.

What is S690QL?
The question of what is S690QL can be briefly answered as follows.
S690QL is a high strength and low alloy structural steel grade. This steel grade has high yield strength (minimum 690 MPa) and excellent toughness properties. "S" steel is used as a standard designation for structural steels, while the number "690" refers to the minimum yield strength of the steel plate. "QL" stands for "high ductility".
S690QL steel is widely used in applications such as machinery operating under heavy loads, cranes, construction machinery, bridges, shipbuilding, mining equipment and the energy sector. Thanks to its high strength, lightweight structure and excellent weldability, it has become a preferred material in engineering projects. In addition, S690QL steel also performs well at low temperatures and can therefore be used in applications that will be exposed to cold weather conditions.
Where is S690QL used?
S690QL steel is used in various application areas due to its high strength and excellent mechanical properties. Here are some areas where S690QL is frequently used:
Construction and Structures: It is used in high-rise buildings, bridges, viaducts, tunnel lines, wind turbines and other structural components. The high strength of S690QL makes structures lighter and stronger.
Heavy Machinery and Equipment: Used in cranes, construction machinery, mining equipment, excavators, crushers, lifting equipment and other heavy machinery. The high strength of S690QL helps such equipment to carry heavy loads and withstand harsh working conditions.
Marine and Shipbuilding: It is used to reinforce steel plates used in shipbuilding and to strengthen structural components. S690QL provides resistance to seawater and corrosive environments.
Mining and Energy Sector: Used in applications such as mining machinery, mine shafts, pipelines, oil and gas equipment. S690QL provides durability in corrosive environments and high stress conditions.
Vehicles: Used in heavy-duty trucks, tankers and railway vehicles. The lightweight nature of S690QL makes vehicles more efficient.
These are some of the main application areas where only S690QL is used. But the durability and properties of the steel grade can offer various application opportunities in different industries.
S690QL Material Properties
S690QL is a high strength structural steel grade and has the following material properties:
Yield Strength: Minimum 690 MPa (Mega Pascal) or higher. Yield strength refers to the stress level at which the material begins to show plastic deformation.
Tensile Strength: Ranges from 770 to 940 MPa. Tensile strength refers to the stress level at which the material resists without rupture at the highest stress level.
Elongation: Minimum 14%. Elongation refers to the amount of elongation of the material after stretching in percentage terms. S690QL has excellent elongation values with high ductility.
Impact Resistance: Minimum 30 J (Joule) or higher at -40°C. Impact strength refers to the material's resistance to impact or impact. S690QL shows good impact resistance even at low temperatures.
Weldability: S690QL steel has good weldability properties. This means that the material performs well during welding operations and durability is maintained after welding.
Low Temperature Performance: S690QL also performs well at low temperatures. This allows it to be used in cold climatic conditions or in low temperature applications.
The material properties of S690QL make it favoured in many industries that require structural strength and light weight. However, it is important to consider more specific properties for a particular application.
