SM490B is a structural steel produced according to Japanese standard JIS G3106, with a strength σb of 490MPa.This standard applies to bridges, ships, vehicles, petroleum storage tanks, manufacturing plants, general construction and various engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, and excavators used in mines and various engineering constructions.
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as EN10025-4 S460ML steel. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
EN10025-4 S460ML steel plate weight: 1) Theoretical weight of EN10025-4 S460ML steel plate: The theoretical weight of a steel plate is the weight calculated based on the nominal size and density of the steel plate (previously called specific gravity). It is closely related to the length, size, and cross-sectional area of the steel plate. 2) The actual weight of EN10025-4 S460ML steel plate: The actual weight of the steel plate refers to the weight obtained through actual weighing, which is more accurate than the theoretical weight.
The Alacero (Latin American Iron and Steel Association) predicts that the EN10025-4 S460ML steel and so on steel consumption in Latin America will reach 66 million tons in 2020, a year-on-year increase of 2.8%. The forecast is influenced by Brazil, the major economy in the region. With the implementation of economic reform measures, the outlook for the Brazilian economy is positive. Our steel business has been occupying a large share in the Latin American market, keeps an increasing trend in recent years, and has won the trust of customers in local. This year we must seize the opportunity to make greater contributions to the local development.
