Hastelloy Alloy is combination of hastelloy and incoloy both members of the “superalloy” family, also known as high-performance alloys. As such, they have several key characteristics in common. They both possess excellent mechanical strength, especially at high temperatures, and they are both highly resistant to corrosion and oxidation.

Standard & Grades

Alloy B-3
Its a member of the nickel-molybdenum family of Hastelloy alloys. Hastelloy B-3 is the alloy in the Hastelloy family that shows best resistance to hydrochloric acid.

Alloy C-276
Its a nickel-molybdenum-chromium wrought alloy that is generally used as corrosion-resistance. Alloy c-276(Hastelloy C276) is among the more well known Hastelloy grades for general corrosion service.

Alloy C-4
Its a nickel-chromium-molybdenum Hastelloy alloy with good high-temperature stability. The Hastelloy C-4 is an Hastelloy grade, that resists the formation of grain-boundary precipitates in weld heat-affected zones.  Hastelloy C-4 alloy also has excellent resistance to stress-corrosion cracking and to oxidizing atmospheres. Hastelloy C-4 is also used in a varity of chemical process environments.

Alloy G
Its an nickel-chromium-iron-molybdenum alloy developed for corrosion resistance in both oxidizing and reduceing media. Alloy G shows good resistance to sulfuric and phosphoric acid. Hastelloy G may further handle both acid and alkaline solutions. 

Hastelloy X
Its a nickel-chromium-iron-molybdenum alloy - has been developed to combine oxidation resistance, fabricability and high-temperature strength.  Hastelloy X is also It has also been found to be resistant in petrochemical applications.
