The oxide film protective layer formed by chromium gives stainless steel excellent corrosion resistance in various environments.
Different types of stainless steel maintain good mechanical properties over a wide temperature range.
Easy to process, form, and weld, making it suitable for the manufacture of complex-shaped products.
Can achieve various surface finishes such as polishing and sanding.
Non-toxic and easy to clean, making it ideal for the food processing and medical fields.
Due to its durability and corrosion resistance, it reduces the need for maintenance during long-term use.
