Testing conducted on plates-
In order to supply the very good quality of S690QL – ESSAR PLATES that are free from faultiness, it is undergoing many effective testing. The tests are conducted by the experts having proper knowledge of testing. To make the testing effective the use of advanced tools are made. The testing is positive material identification test, hardness test, pitting resistance test, mechanical test, chemical analysis, and intergranular test. The other tests like flattening test, flaring test, macro test, and micro test are conducted.

High Strength: The tensile strength of S690QL reaches a relatively high level, which can effectively improve the load-carrying capacity and seismic performance of structures.

Excellent Mechanical Properties: In addition to high strength, it also has excellent fatigue resistance, impact resistance, and low-temperature resistance.

Good Weldability: S690QL fine grain structural steel plates have good weldability and can be welded using conventional welding processes. The low-temperature impact energy of welds and fusion lines is greater than 60J.

Long Service Life: Due to its excellent corrosion resistance and fatigue resistance, S690QL high yield structural steel plates have a relatively long service life.

The application fields of S690QL high-strength plates are extensive, mainly including the following aspects:

Engineering Machinery Field: Used to manufacture key structural components of equipment such as excavators, cranes, and loaders. These machines need to withstand heavy loads and impacts. The high strength of S690QL helps reduce the total weight of equipment, improve energy efficiency and operational flexibility. For example, in large excavator arms and chassis frames, this material can effectively enhance durability.

Mining Equipment: In the mining industry, S690QL is used to manufacture crushers, conveyor systems, and support structures. Its high strength and fatigue resistance make it suitable for heavy-duty equipment handling ores and rocks, extending service life and reducing maintenance requirements.

Bridge Construction: Although not directly used for main beams, S690QL is applied in certain special bridge components such as high-stress connectors or temporary support structures. Its performance contributes to lightweight design, but it needs to comply with relevant bridge specifications.

Shipbuilding and Marine Engineering: In the shipbuilding industry, this material is used to construct parts of tugboats, workboats, and offshore platforms. High strength and corrosion resistance (usually combined with coating systems) are important considerations. It helps increase the payload capacity of ships without adding significant weight.

Heavy Transport Vehicles: Including truck chassis, trailers, and special transport equipment. Using S690QL alloy structural steel plate can reduce the self-weight of vehicles, increase payload capacity, and ensure structural integrity under rough road conditions.

Energy Industry: In some components of wind turbine towers or hydroelectric equipment, S690QL is used to strengthen key load-bearing parts, adapting to long-term use in harsh environments.
