Stainless steel is an iron alloy that comprises 10.5 to 30% chromium. Stainless steel gets its stainless attribute from the chromium-rich oxide that forms an adherent and invisible outer film, it can also contain nickel, manganese, and nitrogen.
The process can be divided into three stages:
Primary Manufacturing: The process begins with the selection and collection of the material that will later be melted. Ferrous scrap is used, to which a certain amount of ferroalloys and other minerals that have undergone a rigorous control process are added, ensuring their safety and quality.
Steelmaking: the scraps are melted in electric arc furnaces with a capacity of over 100 tons, thanks to graphite electrodes that allow high melting temperatures to be reached.
The liquid steel is taken to a converter where it is blown with oxygen and inert gas and ends with the refining of the alloy, reducing the carbon level of the broth, recovering the metal present in the metal oxides and reducing the sulfur content.
It solidifies through a continuous casting machine.
Rolling: In hot rolling, the thickness or diameter is reduced by taking advantage of the greater ductility of the material at high temperatures, cold rolling can also be performed in which the final thickness or diameter is obtained without prior heating.
Once the process is finished, it is delivered to the cutting lines to adapt to the needs of the customers, whether they require finishing or a certain presentation.
