Q690E Steel Description

Q690E high-strength steel plate is a low alloy steel with good impact toughness and welding performance. Q690E grade steel under the GB/T16270-2009 standard of the national standard. Q690E steel plate equivalent to European standard S690QL. The thickness of Q690E steel plate ranges from 3 mm to 500 mm. It is a quenched and tempered high-strength steel plate, commonly used in large lifting equipment. In Q690E steel plate, Q represents the yield strength of the steel plate, 690 represents the yield strength of the steel plate is not less than 690 MPa, the letter E represents the steel plate grade, and E represents the steel plate is impacted at - 40 ° low temperature.

Q690E low alloy high strength steel not only has very high strength, but also has certain toughness, impact resistance, wear resistance, fatigue resistance and easy processing and forming properties. Q690E steel plate is mainly used to manufacture various kinds of engineering machinery with low temperature impact resistance, commonly used in lifting equipment, port machinery, bridge buildings, steel structures, ships, pressure vessels, construction machinery, metallurgical equipment, mining machinery, hydraulic machinery, deck machinery, mining transportation equipment, large support equipment, hydraulic machinery, high-rise building structures, pavement machinery, coal mine hydraulic support and other mechanical equipment and other structural parts.
