S690QL steel is high yield strength structural steel, and it is produced in compliance with EN 10025-6 standard.
EN 10025-6 S690QL steel is usually heat treated using quench and temper techniques.
What is EN 10025-6 S690QL equivalent ASTM steel? A709 grade 100 material is usually considered the EN 10025-6 S690QL equivalent ASTM steel.
Besides, S690QL equivalent ISO steel is E690.

FAQ
Q: What is the difference between S690Q and S690QL?
A: S690Q: Minimum impact toughness tested at -20°C (30J average). → Typical Use: Cranes in temperate climates, quarry equipment. S690QL: Certified for -40°C and below (≥40J impact toughness).
Q: What is S690QL steel equivalent to?
A: Approximate Equivalents of S690QL :
ASTM A514, EN 10149-2 Grade S700MC, AS/NZS 3579 Grade 700, AM 700, Bisalloy 80.
Q: What is the difference between Weldox 700 and S690QL?
A: The versatile Weldox 700 shows excellent formability and can be welded following standard welding procedures. With excellent consistency and hardness, the Strenx S690ql grade has enhanced toughness and superior resistance against fracture induced by stress.
Q: What is S690QL used for?
A: Uses include earthmoving equipment, dump trucks, mobile cranes, drilling rigs, high-speed fans, and bridges. ASTM A514, EN 10149-2 Grade S700MC, AS/NZS 3579 Grade 700, AM 700, Bisalloy 80. S690QL steel plate can be readily formed or bent at room temperature if adequate power is available and proper procedures are used.
Q: What is the difference between S890QL and S690QL?
A: S890QL is a structural steel grade with an even greater yield strength than S690QL.
