Seamless tube and pipe
– ASTM A790, A928
•High resistance to stress corrosion cracking (SCC) in chloride-bearing environments
•High resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfide 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
Wall thickness: 4-60 mm
Lengths up to: 12 m
Due to its excellent corrosion properties, S31803 is a highly suitable material for service in environments containing chlorides and hydrogen sulphide. The material is suitable for use in production tubing and flowlines for the extraction of oil and gas from sour wells, in refineries and in process solutions contaminated with chlorides.
It is particularly suitable for heat exchangers where chloride-bearing water or brackish water is used as a cooling medium. The steel is also suitable for use in dilute sulphuric acid solutions and for handling, organic acids, e.g. acetic acid and mixtures.
The high strength of S31803 makes the material an attractive alternative to the austenitic steels in structures subjected to heavy loads.
The good mechanical and corrosion properties make S31803 an economical choice in many applications by reducing the life cycle cost of equipment.
