The production of stainless steel strip involves precise metallurgical and mechanical steps that ensure corrosion resistance, high strength, and accurate dimensional control.
The process begins with selecting high-quality raw materials including iron, chromium (at least 10.5%), nickel, and additional alloying elements such as carbon, manganese, silicon, molybdenum, and copper. These elements are precisely proportioned to achieve the required stainless steel grade.
The blended raw materials are melted in an electric arc furnace or induction furnace at temperatures around 1600°C. During melting, impurities and gases are removed while the chemical composition is adjusted to precise specifications.
The molten stainless steel is poured into a continuous casting machine, where it forms a semi-finished billet. Controlled cooling and mold temperature directly influence the strip's internal structure and surface quality.
The billet is hot rolled to reduce thickness and achieve the required width. Multiple rolling passes refine the grain structure and enhance mechanical properties.
The strip is immersed in an acidic solution to remove surface scale and oxides. Pickling ensures a cleaner surface that is suitable for later cold rolling and finishing.
Cold rolling further reduces the thickness, improves flatness, and enhances the surface finish. This process ensures high precision and strength required for precision applications.
The strip undergoes annealing to restore ductility, polishing to improve surface brightness, and slitting/cutting to achieve the required width and length. The final product is a high-quality, corrosion-resistant stainless steel strip ready for industrial use.
