Large-thickness A709 grade 50W high strength steel, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.
ASTM 36 is the most common alloy steel. It is used for most building components, including columns, beams, decorations, and completion elements. ASTM A36 A709 grade 50W high strength steel ductility does not allow the alloy to be used as a cable or as reinforcement (reinforcement). However, ASTM A36 is also perfect for most other purposes.
Consumption of A709 grade 50W high strength steel, finished steel products in Latin America in 2019 was 64.2 million tons, down by 5% compared to 67.6 million tons in 2018. The decline in steel consumption in the region reflects the contraction of Latin American economies, particularly the three major economies: Mexico, Argentina and Brazil. These three countries together accounted for 87% of the reduced steel consumption in Latin America. However, our steel materials export volume to those countries did not decrease but show a increasing tendency last year.
