For the A573 Gr 70 CS steel carbon plate construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that A573 Gr 70 CS steel carbon plate 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.
A573 Gr 70 CS steel carbon plate, Q690CF steel plate, also known as CF (CrackFree) steel in the world, is a kind of steel with low carbon equivalent, low PCM value and excellent welding function. It is generally believed that there is no crack in welding without preheating or under low preheating conditions. In order to further improve Q690CF steel strength, TMCP and microalloying skills are also required.
