Haynes Hastelloy® D-205 Corrosion Resistant Alloy
Subcategory: Superalloy; Nickel Base
Key Words: D205
Material Notes: High silicon alloy based on the Ni-20Cr system. Its chief advantages over high silicon-iron based alloys are excellent formability, good resistance to elevated temperature embrittlement, and superior performance In many concentrations of sulfuric acid. D-205 alloy also possesses high resistance to stress corrosion cracking and is considerably more resistant to pitting corrosion than type 316L Stainless and Fe-17Cr-20Ni-5Si alloys.Given these attributes, D-205 alloy constitutes an ideal sulfuric acid, plate-heat-exchanger material. Also the alloy is very useful for all hardware involved with the processing of highly oxidizing media. An added benefit is that the yield strength of D-205 can be more than doubled by age-hardening.
