Rene 41 Alloy：High Temperature Alloys Suitable for Gas Turbine Components
2024-12-11
Lork Group supplies Rene 41 sheet metal that meets AMS 5545 standards. The AMS 5545 specification covers corrosion and heat-resistant nickel alloy in the form of sheet, strip, and plate.
Rene 41 is a precipitation hardenable nickel-chromium alloy containing significant amounts of cobalt and molybdenum, along with lesser amounts of aluminum and titanium. Rene 41 per AMS 5545 exhibits extremely high room and elevated temperature mechanical properties. Ideal for the aerospace industry due to it's increased heat resistance and rigidity. These characteristics make Rene 41 an ideal material for aircraft parts, including:
- Jet engine and missile components
- Afterburner parts, fasteners, wheels, springs, bolts, and buckets
- Gas turbine components, including turbine casings
Thanks to its extreme corrosion and oxidation resistance, Rene 41 is equally suited to marine and land applications.
Chemical Composition
| Element | Percentage |
| Nickel (Ni) | Balance |
| Chromium (Cr) | 18-20% |
| Cobalt (Co) | 10-12% |
| Molybdenum (Mo) | 9-10% |
| Titanium (Ti) | 3-3.3% |
| Aluminum (Al) | 1.5-1.8% |
| Iron (Fe) | 5% max |
| Carbon (C) | 0.06-0.12% |
| Boron (B) | 0.003-0.01% |
With its well-balanced chemical composition and reliability in extreme environments, Rene 41 is the material of choice for demanding industries.
