Outline
Strictly controlling the content of C, Mn, P, S and gas elements in steel is the key factor to improve the purity of molten steel, reduce the segregation of casting blank, and increase the resistance to H2 S corrosion. The proper addition of alloys and the rational formulation of smelting, continuous casting and hot rolling process system is an important link to ensure that the product meets the standard requirements. The chemical composition and process design of X52MS hot rolled coils developed by Rare Earth Steel Plate Plant of Baotou Steel are reasonable, and the steel is pure, uniform in structure and has excellent comprehensive mechanical properties, in particular, it has resistance to hydrogen induced crack and stress corrosion resistance, product quality having reached the international advanced level.
