S32304 1.4362 Corrosion Resistance
General Corrosion
Because of its high chromium content (23%) the corrosion resistance properties of 2304 are almost equivalent to those of 316L.
Corrosion resistance in different organic acids
Corrosion resistance to stagnant sulfuric acid (0,3 mm/year)
Localized Corrosion Resistance
The 23% chromium and 0.1% nitrogen additions explain why 2304 duplex stainless steel tube behaves much better than Alloy 316L when considering pitting and crevice corrosion resistance.
Stress Corrosion Resistance
Stress corrosion resistance test results in chloride containing aqueous solutions ((8ppm 02) PH =7, >1000 h, applied stresses higher than the yield strength) show that Alloy 2304 outperforms Alloys 304L and 316L, due to its high chromium additions and low nickel contents.
This is a typical feature of duplex stainless steels. Alloy 2205 performs still better than 2304 in similar conditions.
Other Corrosion Resistance Properties
Alloy 2304 duplex stainless steel successfully passes most of the standard IC test procedures such as ASTM, A262E, and C tests. Its corrosion rate in boiling nitric acid (65%) is higher than that of Alloy 316L. Due to its high yield strength, the alloy performs well in abrasion/corrosion applications.
