S690QL Structural Steel Plate, S690QL Quenched Steel Plate, S690QL Steel Plate, EN 10025-6 S690QL High Yield Structural Steel Plate, S690QL High Yield Steel Plate, S690QL Plates Supplier in Mumbai India.


Nitya Export is a prominent trader, manufacturer, and supplier of superior quality and High Tensile S690 QL Plate. We deliver these plates to domestic as well as international customers. 690 QL is a universal corrosion resistance grade as it offers excellent resistance even in critical environments. It is a quenched and tempered structural steel plate having superior yield strength. These plates have exceptional power to perform efficiently in all moderate and reducing environments. These plates are highly resistant to severe media such as acetic acid, nitric acid, formic acid, chlorides, sulfuric acid, and other organic chemicals. We produce 690 QL PLATE, which offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. We perform different treatment processes on the plates to improve their quality and performance. We process 690 QL plates by heat treatment and annealing process. These plates offer high weldability and flexibility properties which makes them suitable for all types of structural purposes. The plates are perfectly reliable for any industrial and commercial applications. These plates are widely used in various industrial applications such as lifting equipment, construction, machine building, and heavy transportation. We perform a quenching and tempering process on plates to make them tremendously surface toughened to avoid erosion. This process is carried out under the guidance and examination of our experts.
