Difference Between Duplex 2507 and Zeron 100

The chemical compositions of Duplex 1507 and Zeron 100 are similar, however Zeron 100 contains more cooper and tungsten. The copper content of Zeron 100 provides excellent resistance to corrosion in many non-oxidizing and mineral acids like hydrochloric and suifuric acid.

Comparison Between 2507 and Zeron 100 — Super Duplex Stainless Steel Casting
Alloy	Characteristics	Applications
2507	Superior strength Superior resistance to chloride stress corrosion cracking, crevice corrosion and chloride pitting Low rate of thermal expansion Combination of properties given by austenitic and ferritic structure Good weldability	Desalination Marine Pulp & paper mill Chemical process pressure vessels, heat exchangers and piping Oil and gas industry Offshore oil industry
Zeron 100	Superior corrosion with PREn ≥ 40 Excellent corrosion resistance to stree cracking and mineral acids High resistance to pitting, crevice corrosion, erosion corrosion and corrosion fatigue Good Weldability	Desalination Flue-gas desulfurization Oil and gas industry Pollution control Chemical, pharmaceutical Mining and mineral industries Pulp and paper Power generation Marine industries
