S690QL material is a high-strength, low-alloy hot-rolled structural steel with excellent mechanical properties and corrosion resistance.S690QL plate is heat treated using the quench and temper process and has good welding and bending properties,can be processed by conventional welding methods without reducing its mechanical properties.
S690QL steel has good corrosion resistance and is suitable for working environments with a variety of corrosive media. It is commonly used in construction, ships, bridges, machinery manufacturing and other fields, and is especially suitable for structural components and parts that require high strength and good toughness.
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
