S690QL High Strength Steel
High Strength Low Alloy Product Description
S690QL high tensile steel is a high yield strength structural steel complying with EN 10025-6 standard. S690QL high strength steel has high strength, toughness, wear resistance and weldability.
S690QL high strength sheet metal Product name: S - Structural steel; 690 - Minimum yield strength MPa; Q - Quenched and tempered delivery condition; L - Impact energy tested at -40ºC.
S690QL high strength structural steel typical applications:
S69QL is a very high-strength structural steel that, when used to replace traditional structural steel, can increase load-bearing capacity and reduce structural weight. S690QL high tensile steel sheet uses include earthmoving equipment, dump trucks, mobile cranes, drilling rigs, high-speed wind turbines and bridges.
