steel plates S690QL top manufacturer in Mumbai

Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. steel plates S690QL, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.

The difference between steel plates S690QL, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

In 2019, steel plates S690QL, crude steel production in North America was 120 million tons, down 0.8% year-on-year, among which crude steel production in the United States in 2019 was 87.9 million tons, up 1.5% year-on-year. The crude steel output of the CIS countries in 2019 was 100.4 million tons, down 0.5% year on year.
