S690QL carbon steel plate sheet erw steel pipe pile supplier

Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between S690QL carbon steel plate sheet, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of S690QL carbon steel plate sheet, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.

904L corrosion-resistant steel is developed with various sulfuric acid corrosion applications. 904L corrosion-resistant steel has high chromium content and enough nickel content. The addition of copper makes 904L corrosion-resistant steel have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking, and its pitting corrosion resistance is slightly better than other steels, such as S690QL carbon steel plate sheet.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the S690QL carbon steel plate sheet steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The company is mainly engaged in S690QL carbon steel plate sheet steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work S690QL carbon steel plate sheet together for a better tomorrow.
