TITAN is proud of its long history and successful relationship with Haynes International, Inc., the leading developer, manufacturer and marketer of high-performance nickel-and cobalt-based alloys used in corrosion and high-temperature applications.

TITAN is pleased to be responsible for the first production weldments of C-2000® and the first B-3® Heat Exchanger produced.

Hastelloy Fabrications

TITAN regularly designs, engineers and fabricates the following applications of Hastelloy custom process equipment:

The corrosion-resistant Hastelloy alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of geothermal, solar energy, oil and gas and pharmaceutical. The benefits of Hastelloy process equipment include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication.

The B-3 alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3 alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. The recently developed Hastelloy Hybrid-BC1, will handle stronger non-oxidizing acids than C-type alloys and will tolerate oxidizing impurities that B-type alloys will not.

The most versatile of the Hastelloy alloys are the “C-type” alloys. The C-2000 alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance break-through for chemical process equipment applications.

C-22 alloy is particularly resistant to pitting and crevice corrosion; it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels.

G-30 alloy has been very successful as phosphoric acid heat exchanger tubing and for other process components in the fertilizer industry. G-35 alloy was designed as an improved version of G-30 alloy in these applications of Hastelloy. The high chromium content of both of these alloys make them the premier choices for strong oxidizing solutions and mixed acid pickling services.

Hastelloy Family of Corrosion-Resistant Alloys
Hastelloy B-3 alloy Same excellent resistance to hydrochloric acid and other strongly reducing chemicals as B-2 alloy, but with significantly better thermal stability, fabricability and stress corrosion cracking resistance.
Hastelloy HYBRID- BC1 alloy A new Ni-Cr-Mo alloy with superior resistance to hydrochloric and sulfuric acids, without the drawbacks of the Ni-Mo and Zr materials. Its resistance to these key chemicals is much greater than that of the popular Ni-Cr-Mo (C-type) alloys, yet it shares with them the outstanding resistance to pitting and crevice attack in chloride salt solutions, and even withstands high levels of oxidizing impurities that the Ni-Mo alloys cannot cope with.
Hastelloy C-4 alloy High-temperature stability in the 1200-1900°F (650-1040°C) range as evidenced by good ductility and corrosion resistance. Virtually the same corrosion resistance as alloy C-276.
Hastelloy C-22 alloy Better overall corrosion resistance in oxidizing corrosives than C-4, C-276 and 625 alloys. Outstanding resistance to localized corrosion and excellent resistance to stress corrosion cracking. Best alloy to use as universal weld filler metal to resist corrosion of weldments.
Hastelloy C-22HS alloy This alloy was designed to exhibit corrosion resistance comparable to other C-type alloys, but which can be heat treated to obtain approximately double the yield strength.
Hastelloy C-276 alloy Versatile, corrosion resistant alloy. Very good resistance to reducing, and mildly oxidizing corrosives. Excellent stress corrosion cracking resistance with very good resistance to localized attack.
Hastelloy C-2000 alloy Most versatile, corrosion resistant alloy with excellent resistance to uniform corrosion in oxidizing or reducing environments. Excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy.
Hastelloy G-30 alloy Many advantages over other metallic and non-metallic materials in handling phosphoric acid, sulfuric acid, nitric acid, fluoride environments and oxidizing acid mixtures.
Hastelloy G-35 alloy Excellent resistance to corrosion in highly oxidizing media and acidic chloride environments.
Hastelloy N alloy Good resistance to aging and embrittlement and good fabricability. It has excellent resistance to hot fluoride salts in the temperature range of 1300°F to 1600°F (705°C-870°C).
