Hastelloy C276 and B2 resist oxidising and reducing acids, wet chlorine and chlorinated organics that destroy stainless and even Monel. They appear in chlor-alkali, fine chemical, pharmaceutical and pollution control service, usually in small numbers and high cost.
Because these alloys are expensive and often long-lead, Hastelloy bodies and internals hold value even when worn or partially disassembled. Identification is everything: markings, certificates or a positive material identification report.
Review points
What decides the value of hastelloy valves
Alloy grade
C276 and B2 behave differently. The grade marking determines both application and value.
Certification
Material certificates or PMI reports are expected at this value level.
Condition
Even heavily worn Hastelloy parts have alloy value, which sets a floor.
Selling it
How to present the lot
Count by size and pattern, and note the marking on the body. If you have certificates, include them; if you do not, say so rather than implying they exist.
Do not separate trim from bodies to sell them individually unless the trim is clearly identifiable and valuable on its own. In most cases the assembly is worth more together.
Questions sellers ask
Do you buy Hastelloy parts and trim?
Yes, including internals separated from the body, when they can be identified.
How do you verify the alloy?
Certificates, markings, or a PMI test we can arrange. We do not buy unidentified high-nickel material as Hastelloy.
Are these worth buying used?
Yes. The alloy value alone often justifies it.
