René 41 Scrap Buyer and Seller
René 41 is one of the older wrought superalloys, and most of what reaches the scrap market is sheet trim and retired engine parts rather than castings. Mipra Steel handles it as its own grade so that its 10% molybdenum is not lost in a mixed superalloy lot.
Sell René 41 Scrap
Tell us the form (sheet trim, bar ends, forgings, retired parts), weight, location and any tags or certificates naming AMS 5545, AMS 5712 or Haynes R-41. A reading showing molybdenum near 10% with cobalt near 11% helps most. We review incoming enquiries and respond with relevant next steps.

What Is René 41?
René 41 is a high-strength wrought alloy for gas-turbine sheet and bar parts, produced today by Haynes International as HAYNES R-41. The Haynes data sheet describes it as a vacuum-melted, precipitation-hardening nickel alloy that keeps high strength in roughly the 650 to 980°C (1200 to 1800°F) range with good oxidation resistance. Strength comes from solution annealing followed by ageing; in the annealed condition it forms much like 18-8 stainless, though it is stronger and resists forming more.
Its chemistry stands out for molybdenum. At about 10%, René 41 carries more than twice the molybdenum of Waspaloy and more than the newer Haynes 282, which Haynes notes is replacing R-41 in many applications because it is easier to fabricate. For a scrap buyer that molybdenum, together with 11% cobalt, is what makes a clean René 41 lot worth keeping apart.
The name is written several ways on buying lists and in searches: René 41, Rene 41, R-41 and Haynes R-41 all mean the same alloy. AMS 5545 covers sheet, strip and plate, AMS 5712 bar and forgings, and AMS 5800 welding wire.
René 41 is listed with the René alloys. Unlike most of that family, which are cast blade alloys, it is wrought. HAYNES and R-41 are trademarks of Haynes International, used here only to identify material.
René 41 Chemical Composition
Nominal composition in weight per cent from the Haynes International data sheet for HAYNES R-41 alloy (H-3056C). The AMS 5545 title gives the same alloy as 54Ni-19Cr-11Co-9.8Mo-3.2Ti-1.5Al-0.006B.

How René 41 Scrap Is Identified
| Reading | Points to |
|---|---|
| Molybdenum about 10% with cobalt about 11% | René 41 |
| Molybdenum about 4% with cobalt about 13.5% | Waspaloy |
| Molybdenum about 8.5%, titanium about 2% | Haynes 282 |
| Cobalt about 18.5% with molybdenum about 4% | Udimet 500 or Udimet 700 |
| Iron well above 5% | Another alloy or steel mixed in |
Handheld XRF reads molybdenum, cobalt, titanium and chromium well, so René 41 is one of the easier wrought superalloys to confirm. Haynes 282 is the alloy most likely to be confused with it in sheet form; its lower titanium and molybdenum separate the two. See XRF testing of nickel alloys.
René 41 Scrap Forms
| Form | Typical source | Note |
|---|---|---|
| Sheet and strip trim | Fabrication of afterburner and nozzle parts | The commonest form; keep free of other alloys from the same shop |
| Bar ends and forging offcuts | Fastener and ring makers | Tags and certificates usually survive |
| Retired engine parts | Overhaul of older military and commercial engines | Check for coatings, braze and attached hardware |
| Turnings | Machining of bar and forgings | Single-grade, dry turnings only |
What Sets the Price of René 41 Scrap
- Contained nickel, cobalt and molybdenum.
- Proof of grade: AMS tags, certificates or a clean set of readings.
- Form: solids above turnings; clean trim above coated parts.
- Contamination with Waspaloy, Haynes 282 or steel hardware.
- Lot size and location.
No price list is published; offers are dated because nickel, cobalt and molybdenum move separately.
