S690QL vs S690QL1 steel properties table

Since the beginning of this year, the global S690QL vs S690QL1 steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global S690QL vs S690QL1 steel tube industry will also suffer from the "flash collapse" of international oil prices in March.

The work performance of S690QL vs S690QL1 etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
