For the density of A573 Grade 70(A573 Gr 70) construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that density of A573 Grade 70(A573 Gr 70) steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.
With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of density of A573 Grade 70(A573 Gr 70) etc. steel material.
Main density of A573 Grade 70(A573 Gr 70) production plants: Wugang, Baosteel, Laiwu Steel, Angang, Baotou Steel, BBN Steel, Katalor Industry
Pressure vessel plates are used to manufacture steel plates for steam boilers, pressure vessels and other pressure vessel structures. Because this kind of steel plate is subjected to certain air pressure and water pressure, and the use environment of different temperatures, such as high, medium and low temperature, etc., the requirements for this kind of steel plate are relatively strict.
