Hastelloy

Hastelloy is a nickel-based corrosion-resistant alloy, which is mainly divided into nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is used in aviation and chemical fields.

American company
The company's predecessor, Haynes Stellite Work, was founded in 1921 in Kokomo, Indiana, USA, and has a history of 92 years. It has been innovating and inventing in production and research for more than 90 years. Thus ranking first in the world in the field of high alloys.
Haynes International focuses on the production and development of products. Mainly engaged in the development and production of high quality corrosion resistant and high temperature resistant nickel-cobalt alloys. The company's expert technicians provide further customer service and technical support worldwide. Haynes' service centers and branches provide customers with timely supply of sheets, rods, tubes, forgings, flanges and connectors [1].

definition
Hastelloy is the general name for the commercial grades of nickel-based corrosion-resistant alloys produced by Hastelloy International. Including nickel molybdenum Hastelloy B-2, nickel chromium molybdenum Hastelloy C-4 and the like.
Hastelloy grades include the following grades:
HASTELLOY B-2 Nickel-Molybdenum Alloy, an excellent upgraded version of HASTELLOY B-3 B-2 in a reducing environment, has excellent corrosion resistance to any temperature and concentration of hydrochloric acid.
HASTELLOY C-4 has good thermal stability and good toughness and corrosion resistance at 650-1040 degrees Celsius.
HASTELLOY C-22 has better resistance to uniform corrosion in oxidizing medium than C-4 and C-276, and has excellent corrosion resistance to local Hastelloy Hastelloy. HASTELLOY C-276 has good resistance to oxidizing and moderate reducing corrosion. Ability, excellent resistance to stress corrosion. HASTELLOY C-2000 The most comprehensive corrosion-resistant alloy with excellent resistance to uniform corrosion in both oxidizing and reducing environments.
HASTELLOY G-35 G-30 upgraded product, better corrosion resistance and thermal stability Excellent HASTELLOY G-30 high chromium content nickel-based alloy, excellent performance in phosphoric acid and other strong oxidizing mixed acid medium.
HASTELLOY X Comprehensive high strength, oxidation resistance and easy processing characteristics Each of the above grades has specific chemical composition, mechanical properties, and has its own strengths. It is not possible to generalize the characteristics of Hastelloy.
