As a professional EN standard high-strength steel supplier with 20+ export experience, GNEE STEEL stocks full-size S690QL plates complying with EN 10025-6, fully equivalent to DILLIMAX 690, WELDOX 700, NAXTRA 70.

 

 

High yield strength

S690QL Plates have minimum yield strength of 690 MPa, which makes them incredibly strong & durable. This strength is achieved through the quenching and tempering that hardens the steel.

 

Excellent toughness

The toughness of the S690QL plate is outstanding, which means it can withstand impact and resist fracture. This makes them ideal for use in heavy-duty applications where durability is critical.

 

Good weldability

Despite their high strength & toughness, these plates are relatively easy to weld. This makes them ideal for construction and other industries where welding is necessary.

 

Corrosion Resistance

They have good corrosion resistance, making them suitable for use in harsh environments or applications where they will be exposed to moisture or chemicals.

 

 

S690QL Steel Plates have a wide range of uses in various industries, including:

 

1.S690QL Steel For Construction Machinery.

S690QL builds critical structural parts for excavators, cranes and loaders. Subjected to heavy loads and impacts, this high‑strength steel cuts total equipment weight, boosts energy efficiency and maneuverability. It strengthens large digging arms and chassis frames reliably.

 

2.S690QL Steel For Mining Equipment.

S690QL serves for crushers, conveyor assemblies and support frames in mines. Thanks to high strength and fatigue resistance, it performs well on heavy‑duty ore‑processing machines, prolonging service cycles and cutting maintenance work.

 

3.S690QL Steel For Bridge Construction

Though not adopted for main bridge girders, S690QL is used for special bridge components including high‑stress connecting parts and temporary supporting structures. Its mechanical properties enable lightweight design subject to relevant bridge‑design codes.

 

4.S690QL Steel For Shipbuilding and Offshore Engineering

This grade of steel forms partial structures of tugboats, work vessels and offshore platforms. High strength and corrosion resistance (generally paired with coating systems) are core considerations. It raises load‑carrying capacity without substantial weight gain.

 

5.S690QL Steel For Heavy‑Duty Transport Vehicles

Applications cover truck chassis, trailers and special transport equipment. S690QL cuts curb weight and increases payload while maintaining structural integrity under rough road conditions.

FAQ:

What grade is S690QL material?

S690QL (Material Number 1.8928) is a high-yield, quenched and tempered structural steel compliant with the EN 10025-6 standard. It guarantees a minimum yield strength of 690 MPa, allowing for lighter, high-payload fabrications like mobile cranes, mining equipment, and bridges.

 

What is the difference between A514 and S690QL?

ASTM A514 is high strength low alloy steel. it is designed for heavy duty applications S690QL is a quenched and tempered high strength low alloy steel which has good weldability and ductility.

 

What is the effective use of high strength S690 steel in construction?

The high strength S690 steels have an excellent strength-to-self-weight ratio, and they are highly efficient to be used in heavily loaded structures. Typical applications include piles and columns in buildings and supporting members in bridges.

 

What is the difference between S700MC and S690QL?

S700MC and S690QL are both high-strength structural steels but serve different primary purposes. S700MC is a thermo-mechanically rolled steel optimized for cold forming and lightweight components, whereas S690QL is quenched and tempered, offering superior impact toughness and durability under heavy or dynamic loads.

 

What is the difference between S890QL and S690QL?

What is the main difference between S690QL and S890QL? The primary difference is yield strength - 690 MPa vs 890 MPa. S890QL is stronger and lighter, but S690QL is easier to weld and more cost-effective.
