UNS S31803 : Duplex Stainless : ASTM A182 (VO1.01), A276 (VO1.03), A479 (VO1.03), BS EN 10088
Trade Name Zeron 25 (4)
The characteristic feature of duplex stainless steels is their dual phase microstructure, comprising of approximately 50% of austenitic and 50% of ferrite. This provides the material with an excellent combination of high strength and corrosion resistance.
Pitting Corrosion - The resistance to pitting corrosion may be compared to other grades by using the pitting index PREN. The higher the PREN value, the better the pitting resistance.
Condition: Solution Annealed and Water Quenched.
