properties and uses of Hastelloy B and C.
Answers
Answer:
first make me as brain list then I will answer your question
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.
