Flat steel is divided into galvanized flat steel, carbon flat steel, stainless steel flat steel, etc. according to the material. Flat steel can be divided into hot-rolled flat steel and forged flat steel according to the forging process. JIS carbon steel SM490YA CS plate, Hot-rolled flat steel is a potential-rolled long steel with a rectangular cross-section for general use. Forged flat steel is a long steel plate with a rectangular cross section that is forged. Hot-rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery. The thickness of the flat steel is 8-50mm, the width is 150-625mm, and the length is 5-15m.

Stainless steel plates are alloy steels with very good strength, precision, and toughness, and can be used for many purposes in processing. The surface of the stainless steel plate is smooth and beautiful, and it can be processed into various high-end hardware products. JIS carbon steel SM490YA CS plate, Stainless steel plates have outstanding characteristics and a wide range of applications. Stainless steel plates are used outside of buildings in coastal areas to prevent corrosion. The seawater has strong acidity and alkalinity. General steel plates are prone to rust and corrosion for a long time.

The JIS carbon steel SM490YA CS plate steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the JIS carbon steel SM490YA CS plate internal quality of the steel.
