Hot-rolled coil is a steel product produced through a hot-rolling process, in which preheated steel billets are rolled into flat plates of a certain thickness at high temperature. The main characteristics of this steel are its excellent ductility and toughness, making it easy to form and process in industrial applications. The 20Cr13 stainless steel hot-rolled coil belongs to the martensitic stainless steel family and is a chromium-rich steel. Its main components include iron, approximately 12% to 14% chromium, a small proportion of carbon, and trace amounts of nickel, manganese, silicon, phosphorus, and sulfur. 20Cr13 stainless steel hot-rolled coils are known for their excellent hardness and strength, widely used in applications requiring wear resistance and corrosion resistance, such as cutlery, medical instruments, valves, pumps, and other industrial applications.
