How to predict the price trend of medium and heavy plate, S420ML steel grade? First, the output of steel plate. The future annual plan of the major steel mills can be learned timely through the official website. Second, market demand forecast. Third, overall data of the global steel, judgment and rectification of foreign political trade, such as tariff. Of course, we should also consider the transportation cost and other factors, which will also affect the price of medium and heavy plate, S420ML steel grade.
ASME SA514 grade H alloy steel coil element composition%C: 0.12-0.21, Si: 0.20-0.35, Mn: 0.95-1.30, P max.: 0.035, S max.: 0.035, Cr: 0.40-0.65, Ni: 0.30-0.70, Mo: 0.20-0.30, V: 0.03-0.08, B: 0.001-0.005The mechanical properties in thickness (mm)T≤65Yield strength (≥Mpa): 690Tensile strength (Mpa):760-895Elongation in ≥, %: 18
The work performance of S420ML steel grade etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. S420ML steel grade Heat treatment process refers to the ability to change the microstructure and properties of S420ML steel grade after heat treatment, including hardenability, hardenability, temper brittleness, etc.
