Hastelloy

Hastelloy˘ X

Hastelloy X is a Nickel-Chromium-Iron-Molybdenum alloy with an exceptional combination of oxidation resistance, ease of fabrication and high temperature strength. It has also been found to be exceptionally resistant to stress corrosion cracking in petrochemical applications. Hastelloy X is also known as Inconel HX, Nicrofer 4722 Co, and Pyromet 680.

Hastelloy˘ C-2000

This alloy was developed to broaden the application range of one alloy. With the addition of Copper to the Nickel-Chromium-Molybdenum system, Hastelloy C-2000 is resistant to an extensive range of corrosive chemicals, including sulphuric, hydrochloric and hydrofluoric acids. The combination of Molybdenum and Copper provide excellent corrosion resistance to reducing media, while the high Chromium content gives good oxidising resistance.

Hastelloy˘ C-276

This Nickel-Molybdenum-Chromium alloy with the addition of Tungsten, has excellent corrosion resistance in a wide range of corrosive media and is especially resistant to pitting and crevice corrosion. Hastelloy C-276 is also known as Nicrofer 5716, Superimphy 276, and Inconel C-276.

Hastelloy˘ C-22

A Nickel-Chromium-Molybdenum alloy with better overall resistance and versatility than any other NiCrMo available. It has excellent resistance to localised corrosion and to a variety of mixed industrial chemicals. Hastelloy C-22 is also known as Nicrofer 5621, Superimphy C22, and Inconel 622.

Hastelloy˘ C-4

This Nickel-Chromium-Molybdenum alloy tolerates high temperatures and gives a design freedom in areas where weld geometry makes excessive heat build-up unavoidable. Resistance to general and localised corrosion and stress corrosion cracking is generally similar to Hastelloy C-276. Hastelloy C-4 is also known as Nicrofer 6616.

Hastelloy˘ B-3

This Nickel-Molybdenum alloy gives excellent resistance to hydrochloric acid at all concentrations and temperatures from ambient to high. It also withstands sulphuric, acetic, formic and phosphoric acids and other non oxidizing media. B-3 also has excellent resistance to pitting corrosion and to stress-corrosion cracking. Hastelloy B-3 is not recommended in the presence of ferric or cupric salts.
