S32520 is also known as UNS S32550 or Bs En 1.4507. It is a high chromium nickel super duplex stainless steel. It has very good resistance against corrosion and pitting against corrosives such as sulphuric acid. It is advisable not to use this type of steel in high temperature applications where tensile strength of a material is 770 Mpa and yield strength is 550 MPa. They are used in oil refining, fertilizer, papermaking, petroleum, high temperature heat exchangers. etc.
