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. Because each melt is made to one grade, Haynes 230 hidden in a Hastelloy X lot shifts the heat chemistry and the buyer adjusts the offer to match.
What are the UNS numbers of Hastelloy X and Haynes 230?
Hastelloy X is UNS N06002 and Haynes 230 is UNS N06230.
Which has more nickel, Hastelloy X or Haynes 230?
Haynes 230, with about 58.7% nickel against about 48.4% in Hastelloy X, using the nominal values on this site.
