Difference Between Duplex 2507 and Zeron 100

The chemical compositions of Duplex 1507 and Zeron 100 exhibit similarities, but Zeron 100 possesses higher levels of copper and tungsten. The elevated copper content in Zeron 100 imparts exceptional resistance to corrosion when exposed to various non-oxidizing and mineral acids, such as hydrochloric and sulfuric acid.
