Carbon equivalent value CEV of SA36 carbon steel plate sheet

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, SA36 carbon steel plate sheet flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the SA36 carbon steel plate sheet construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU SA36 carbon steel plate sheet steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.

High strength steel is a kind of steel often used in engineering construction. With the improvement of technical level, the research and development of high strength steel in China has made remarkable achievements. The application of high strength steel SA36 carbon steel plate sheet in the construction field can reduce the steel consumption and building volume, and improve the building weight. That is one of the important reason why the high strength steel is so warmly welcomed nowadays.
