Hastelloy B/B2/B3 Round Bar
Common Trade Names: Hastelloy B, NS3201,UNS N10001
Hastelloy B is a face-centered cubic lattice structure.
By controlling the content of Fe and Cr at a small value, the brittleness of processing is reduced and the precipitation of N4Mo phase between 700 ℃ and 870℃ is prevented.in the reduction of medium with very good corrosion resistance, such as a various temperature and concentration of hydrochloric acid. In the middle of the concentration of sulfuric acid solution (or contain a certain amount of chloride ions) also has very good corrosion resistance. At the same time can be used to acetic acid and phosphoric acid environment. Alloy material suitable only in the metallurgical structure and pure crystal structure in order to have the best corrosion resistance.

Why Hastelloy B ?
• Excellent corrosion resistance for reductive environment.
• Excellent resistance to sulfuric acid (except for concentrated) and other non-oxidizing acids.
• Good resistance to stress corrosion cracking (SCC) caused by chlorides.
• Excellent resistance to corrosion caused by organic acids.
• Good corrosion resistance even for welding heat affect zone due to low concentration of carbon and silicon.
Hastelloy B Application field：
Widely used in the chemical, petrochemical, energy manufacturing and pollution control related processing and
equipment,especially in the processes dealing with various acids (sulfuric acid, hydrochloric acid,
phosphoric acid, acetic acid and so on.
