What is the tensile strength of S690?
S690 Properties
Tensile strength: between 770 and 940 MPa, ensuring excellent load-bearing capacity. Good weldability: achievable with advanced techniques and controlled parameters. Improved toughness: even under dynamic loads and challenging environments.
What is the standard for S690Q?
S690Q – structural high-strength steel with minimum yield strength of 690 MPa supplied in quenched and tempered condition (Q). Plates of S690 steel grade comply with EN 10025-6 standard.
What are the properties of S690QL?
S690Q is a high-strength, quenched and tempered structural steel with a minimum yield strength of 690 MPa for thicknesses up to 50 mm. Its properties include a high tensile strength of 770-940 MPa, excellent toughness, good weldability, and fatigue resistance. It is produced for applications where high strength-to-weight ratio is critical, such as in cranes, bridges, and heavy equipment.
What is the difference between S690QL and A517?
S690QL and A517 are both high-strength, quenched, and tempered steel plates, but they differ in their governing standard, primary applications, and specific mechanical requirements.
S690QL is a European structural steel, whereas A517 is an American standard for pressure vessels.
