According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions; Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel acier S690QL equivalent is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.
Due to the high cost support of raw material end and the re attack of environmental protection and production restriction of steel enterprises, the market supply is limited and acier S690QL equivalent traders are willing to support the price. However, the influence of off-season continues, the terminal demand is greatly reduced, and the downstream merchants mainly purchase on rigid demand. The overall delivery performance is not good. It is expected that the acier S690QL equivalent price will be adjusted steadily tomorrow.
As the basic processing materials and building materials, the medium and heavy plate is an important purchasing material for many manufacturers and construction enterprises, so the grasp of the latest price rise and fall of the medium and heavy plate, acier S690QL equivalent is directly related to the cost and profit of enterprises. Therefore, it is necessary for purchasing staff to learn how to predict. Today, we share the latest price rise and fall skills, how to predict the price trend of medium and heavy plate, acier S690QL equivalent.
South Korean acier S690QL equivalent steel industry said that the slowdown in economic growth superimposed on the impact of the epidemic, steel demand weakened, exports were sluggish, enterprises are facing huge operating pressure. Due to the delay in the resumption of work of Chinese acier S690QL equivalent steel enterprises, the steel inventory is growing rapidly. According to statistics, China's steel circulation inventory reached 23.75 million tons in February, the highest since 2006, with an estimated total inventory of 33.45 million tons.
