# Cast stainless steels

Cast stainless steels are stainless-steel materials produced by casting, combining corrosion resistance with the ability to form complex component shapes. Their composition and mechanical behaviour vary by grade, and they are used for corrosion-resistant cast components such as pumps, valves and process equipment.
