Sandvik SAF 31803
- High resistance to stress corrosion cracking in chloride-bearing environments
- High resistance to stress corrosion cracking in environments containing hydrogen sulphide
- High resistance to general corrosion, pitting, and crevice corrosion
- High resistance to erosion corrosion and corrosion fatigue
- High mechanical strength - roughly twice the proof strength of austenitic stainless steel
- Physical properties that offer design advantages
- Good weldability
Applications
Due to its excellent corrosion properties, Sandvik SAF 31803 is a highly suitable material for service in environments containing chlorides and hydrogen sulphide. Sandvik SAF 31803 is mainly available as heat exchanger tubing and is particularly suitable for heat exchangers where chloride-bearing water or brackish water is used as a cooling medium.
The high strength of Sandvik SAF 31803 makes the material an attractive alternative to the austenitic steels in structures subjected to heavy loads.
The good mechanical and corrosion properties make Sandvik SAF 31803 an economical choice in many applications by reducing the life cycle cost of equipment.
