The JIS SM520C plates tensile strength Mpa from BBN

Carbon steel JIS SM520C plates is an iron carbon alloy with carbon content less than 2.11% and a small amount of silicon, manganese, sulfur, phosphorus and other impurities. Carbon steel inevitably contains some impurity elements during smelting, which has a great influence on the performance and quality of steel, so it should be controlled. The quality of carbon steel is mainly measured by the content of sulfur and phosphorus. The lower the JIS SM520C plates content of sulfur and phosphorus, the better the quality of carbon steel.

JIS SM520C plates and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as JIS SM520C plates. 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.
