How to choose between Hastelloy 276, titanium alloys Ta1, Ta2Tc4, and dual-phase stainless steels?

Selecting the right corrosion-resistant alloy is critical for equipment longevity. Hastelloy C-276 provides the broadest resistance for harsh chemical processing with strong acids like HCl and H₂SO₄. Titanium Grade 2 is virtually immune to seawater and oxidizing chloride environments, ideal for marine and desalination. Duplex 2205 offers superior chloride stress corrosion cracking resistance at a cost-effective price point. Material choice depends on specific chemistry, temperature, and budget. Consult corrosion data for optimal selection.
