Summary
Both are sheet alloys for gas turbine combustors and industrial furnaces, so they come back as the same kind of trimmed sheet, formed parts and retired combustor liners.
Haynes 230’s 14% tungsten is the signature and makes it the more valuable of the two. Hastelloy X reads as a high-iron Ni-Cr-Mo alloy with no niobium, which also separates it from Inconel 625. See Hastelloy X scrap and Haynes 230 scrap.

FAQ
What is the main difference between Hastelloy X and Haynes 230?
Hastelloy X has about 22% chromium, 18.5% iron and 9% molybdenum. Haynes 230 has about 22% chromium and 14% tungsten with very little iron.
Can Hastelloy X and Haynes 230 scrap be mixed?
No. Keep them separate. A melter buying either one needs its chemistry to stay within the grade’s limits, and mixing can mean a re-sort or a different valuation.
