Competitive price S690QL steel equivalent to grade 50 in stock

S690QL steel equivalent to grade 50, carbon steel plate is a kind of steel plate, and it is the abbreviation of common carbon structural steel. The carbon steel plate belongs to a large category of steel, including Q235, SS400, A36, SM400, ST37-2, etc. Due to the different names in various countries, the carbon steel standards implemented are also different. The ordinary carbon structural steel, S690QL steel equivalent to grade 50 is mainly used for construction machinery, mining machinery, heavy vehicles, bridges, pressure vessel plate and other engineering structures.

The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel S690QL steel equivalent to grade 50. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.

If the chromium content in S690QL steel equivalent to grade 50 alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s S690QL steel equivalent to grade 50 domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
