Specification of S690QL Steel Plates

S690QL steel plates are typically used in a variety of industries, including heavy transportation, machine building, and construction. High levels of resistance to both high and low temperatures as well as non-reactivity to acidic fluids have been demonstrated for S690QL. It comes in a variety of finishing options.
Designers also favor these plates because of how lightweight they are. They enable structures to be designed more efficiently and offer significant cost savings in the processing and handling of materials. These plates are both very durable and simple to manufacture.

In addition, the S690QL steel plate offers high tensile strength and is suited for bending. These properties make it ideal for structural applications, especially in heavy-duty vehicles and trailers. It also provides improved energy efficiency and safety.

High-quality alloys are used to fabricate S690QL steel plates. They go through thorough testing as well as strict oversight during production. They are given to you quenched and tempered. They are consequently more durable than other common structural steels.

Bending and welding

The bending and welding characteristics of high-strength steels have been studied in a number of different ways. These studies have concentrated on the impact of different welding parameters on the weld’s microstructure. The ideal welding technique for high-strength steel has been determined using these findings.
The bending and welding characteristics of S690 QL structural steel were examined during this study. Additionally, optical emission spectroscopy was used to determine the test material’s chemical makeup. The information can be used to forecast how the S690QL will behave mechanically in challenging circumstances.

The test material was quenched and tempered steel grade S690QL. It was welded using friction stir welding. The joints were made without filler metal. The maximum stress-relieving temperature of S690QL is 560 C/1040F.

Welded joints exhibit a regular shape with a slight concave root on the face side. The width of the heat-affected zone is uniform throughout the thickness of the welded joint.
