Material Summary

Duplex S32205 are the most common duplex grades in the market. They have very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength. They are widely used in oil & gas, hydro power, pressure vessels, pulp & paper, structural components and chemical tankers. The alloys are not intended to be used at temperatures above 300°C due to embrittlement..
S32205 are characterized by:
High resistance to stress corrosion cracking in halide containing environments.
High resistance to pitting and crevice corrosion.
High resistance to general corrosion.
High mechanical strength.
High resistance to erosion corrosion and corrosion fatigue.
