S690QL steel plate is a high-strength low-alloy steel plate with high strength, excellent toughness and good welding properties. It is widely used in engineering machinery, mining equipment, ships, bridges, buildings and other structural fields. The designation S690QL refers to a minimum yield strength of 690 MPa.
S690QL steel plate has very high yield strength and tensile strength,much higher than traditional carbon steel plate, making it very popular in applications requiring high strength.
S690QL Material Technical details
S - is for Structural Steel
690 - is for minimum yield strength (MPa)
Q - is for Quenching & Tempering and
L - is for low attain toughness testing temperature
