Short answer: Inconel and Hastelloy are both nickel base superalloys, but Inconel leads on high-temperature strength and oxidation for turbine and exhaust duty while Hastelloy leads on resistance to reducing acids and chlorides for chemical and flue-gas duty, so the choice turns on service temperature and the corrodent, with Inconel chosen for heat and Hastelloy chosen for aggressive chemistry, and both supplied as certified bar, plate and tube.
At a Glance
What the Two Alloys Are
Both are nickel base with chromium and molybdenum, with the basis in our Nickel Alloy Grades Guide and strength notes in our Metal Strength Comparison; the superalloy basis is in our Superalloy Supplier.
Temperature and Corrosion
Inconel keeps strength and scale resistance at high heat and Hastelloy resists acids and wet chlorine, with resistance detail in our Corrosion Resistance Guide and chemical context in our Chemical Processing Guide.
Fabrication
Both weld with matching filler and need low heat to avoid sensitization, with welding in our Welding Joining Guide and machining in our Machining Guide; finish is in our Surface Treatment Guide.
Quality and Sourcing
Superalloy stock is checked by inspection and PMI, with methods in our Quality Inspection Guide; buyers confirm grade via our Mill Test Certificate Guide and pack per our Export Packing Guide.
