The Brazil steel is facing a "crisis of demand" as the epidemic of new crown pneumonia spreads in Brazil. The demand for A572 grade 50 CS steel carbon plate and so on steel will be reduced by 50% in April. The demand for the second quarter will be 40% lower than that in the first quarter. The demand for this year will be reduced by 20% compared with the same period this year. In 2019, Brazil's apparent steel consumption was 20.6 million tons, a year-on-year decrease of 2.7%; crude steel production dropped to 32.33 million tons, the lowest since 2016 (30.2 million tons).
The rolling pipe is made by steel plate with welding process. The rolling pipe is mainly used for conveying water, gas, air, oil and hot water or steam, etc. The rolling pipe has the following characteristics. First, it is easy to process. Welding can be done directly on the basis of steel plates, A572 grade 50 CS steel carbon plate. Second, the diameter is large, and various large-diameter rolling pipes can be directly customized and processed. Third, the processing speed is fast, saving processing time. Fourth, a small amount of customization can be used for trial proofing to avoid excessive waste.
"Turkey has filed a lawsuit against EU steel import tariffs with the world trade organization, the trade ministry said Friday. In February 2019, the European Union said that the sharp increase of Turkish steel imports A572 grade 50 CS steel carbon plate seriously threatened the steel producers in member countries. The European Union has set import quotas for 26 kinds of steel products and imposed a 25% tariff on future steel products for three years.
