S690QL High Yield Strength Steel

What is S690QL ?

S690 QL is a special type of Alloy Quenched & Tempered steel plate having YS (i.e. Yield Strength) more than 690. This type of steel is specially used in structural purposes & is compliant with the standard EN 10025:6:2004.
Offering high standards of weldebility and flexibility, this high yield strength plates are best suitable for all kinds of structural purposes.

The material is heat treated using the quench and temper process and has good bending and welding properties. Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.

S690QL Dillimax 690T is a fine grained quenched and tempered steel plate notable for its high strength. S690QL plates are used in a wide variety of engineering applications where strength is important – including cranes, critical structural components in building and stadia and pipes and gates in hydroelectric projects. It is a high strength steel for fixed and mobile equipment under heavy loading.

690QL Plates also have varied Applications:

  1. Heavy transportation
  2. Machine building
  3. Steel constructions
  4. Lifting equipment

S690 QL – Grade Designation
The grade designation of S690 QL is the following: S = Structural Steel
690 = minimum yield strength (MPa)
Q = Quenching & Tempering
L = Low notch toughness testing temperature
