How steel is made?
Iron and steel is an alloy of iron and C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur), and a small amount of other elements. In addition to Fe (iron), the content of C plays a major role in the mechanical properties of steel, so it is collectively referred to as iron-carbon alloy. It is the most important and the most important, most used metal material in engineering technology.
The general rule of carbon steel can be approximated as that the higher the carbon content is, the higher the hardness is, but the greater the hardness, the lower the hardness when the carbon content increases. The hardness of steel materials depends mainly on the chemical composition of the material (steel), high hardness with high carbon content, and heat treatment conditions.
The cyclical fluctuation of steel prices is a comprehensive reflection of the market cycle of the steel industry. It is the result of the chain effect of price-benefit-investment-capacity-supply and demand. Overall, there are several factors that affect steel price changes: First, production costs, which is the basis for changes in steel prices; Second, supply and demand are the key factors affecting changes in steel prices; Third, the market system, defective The market system may amplify the imbalance between supply and demand, causing price fluctuations.
