The production process of stainless steel (or inox) goes through 5 main stages: Preparation of input materials – Melting – Hot rolling – Annealing and pickling system – Finishing the finished product. In which, the annealing and pickling process helps restore the material properties by heat treatment to stabilize the steel crystal structures that have been deformed or displaced during the rolling process. After that, the product is passed through a mixture of cleaning acids and cleaned with high pressure water to remove rust stains. This stage helps remove product defects, and creates a product with perfect physical and mechanical properties. In addition, this step also helps create a thin protective layer (Chromium Oxide) for the product. Stainless steel is a very popular material. The product is applied in most manufacturing and civil industries. Besides, stainless steel also has outstanding aesthetics and durability compared to other materials.
