Competitive price S690QL1 high strength steel plates

Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between S690QL1 high strength steel plates, hot rolled sheet and cold rolled sheet?

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This S690QL1 high strength steel plates production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate S690QL1 high strength steel plates size.

The qualified flat steel has sufficiently high high temperature strength and high temperature plasticity. Therefore, S690QL1 high strength steel plates flat steel is not only required to have high enough normal temperature and instantaneous high temperature tensile strength and plasticity, but also long-term strength and long-term plasticity to ensure long-term safe work at high temperatures, especially under creep leakage conditions. The product thickness is 8-50mm, width 150-625mm, length 5-15m。
