S690QL Steel Description

S690QL plate is a high-strength, low-alloy steel plate widely used in structural engineering projects that require high strength and good weldability.The S690QL steel is heat treated using the quench and temper process and has good bending and welding properties.It also has excellent strength and toughness while maintaining good machinability and weldability.

S690QL steel is a quenched and tempered low-alloy high-strength structural steel.Grade designation of S690QL Steel are as follows:

• S = Structural Steel
• 690 = minimum yield strength (MPa)
• Q = Quenching & Tempering
• L = Low notch toughness testing temperature

High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel. HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.
