What is Rene 95?
Rene 95 (UNS N07095, AMS 5713) is a powder-metallurgy nickel superalloy with about 3.5 % Al and 2.5 % Ti forming a high γ′ fraction, consolidated by HIP of pre-alloyed powder or by extrusion and isothermal forging. HIP plus heat treatment gives 1240 MPa yield, 1620 MPa tensile, 15 % elongation and 45 HRC, the highest strength level in this family, which is why it is used for turbine disks and other rotating hardware. Its practical service limit is 650 °C, it is effectively non-weldable, and machinability is very low (score 12), with residual stress on fatigue-critical surfaces needing close control. Rene 95 has a density of 8.19 g/cm³ (0.296 lb/in³), lighter than 68% of nickel alloy grades. It melts at 1,260°C (2,300 °F). Rene 95 has a yield strength of 1,240 MPa (180 ksi) and a tensile strength of 1,620 MPa (235 ksi) — stronger than 99% of nickel alloy grades. Elongation at break is 15% and the elastic modulus is 210 GPa (30.5 Msi).

Working with Rene 95
Is Rene 95 easy to machine?
Very difficult: use rigid setups, whisker/SiAlON or coated-carbide inserts, low surface speeds (20–35 m/min carbide), heavy flood coolant, and control residual stress/white layer on fatigue-critical surfaces.
Can Rene 95 be welded?
Effectively non-weldable by fusion due to ~3.5 Al + 2.5 Ti strain-age cracking; repairs limited to specialised diffusion/braze or solid-state (inertia/linear friction) joining with post-bond heat treatment.
Can Rene 95 be formed, bent or molded?
No cold forming — the alloy is shaped by HIP of pre-alloyed powder, extrusion and isothermal forging near 1100 °C at low strain rates in the sub-solvus window.

Rene 95 — frequently asked
What is Rene 95 used for?
Rene 95 is typically used for turbine disks, aerospace rotating hardware, compressor disks and spacers, blisks and rotor hubs, seal rings and retaining rings and shaft and coupling components for gas turbines. In short: highest-strength PM disk alloy; sub-solvus isothermal forging; 650 °C service limit.
What is the yield strength of Rene 95?
Rene 95 has a typical yield strength of 1,240 MPa (180 ksi) and a tensile strength of 1,620 MPa (235 ksi) — stronger than 99% of nickel alloy grades. Strength varies by condition: see the 5 listed tempers.
Is Rene 95 easy to machine?
Not especially — machinability is rated not recommended (12/100, worse than 86% of nickel alloy grades). Very difficult: use rigid setups, whisker/SiAlON or coated-carbide inserts, low surface speeds (20–35 m/min carbide), heavy flood coolant, and control residual stress/white layer on fatigue-critical surfaces.
Can Rene 95 be welded?
Not readily — weldability is rated not recommended (8/100). Effectively non-weldable by fusion due to ~3.5 Al + 2.5 Ti strain-age cracking; repairs limited to specialised diffusion/braze or solid-state (inertia/linear friction) joining with post-bond heat treatment.
What surface finishes work on Rene 95?
Shot-peen or low-plasticity burnish fatigue-critical surfaces; can be diffusion-coated or aluminised for oxidation, and takes a fine mechanical/electrolytic polish; no anodising.
Can Rene 95 be formed, bent or molded?
No cold forming — the alloy is shaped by HIP of pre-alloyed powder, extrusion and isothermal forging near 1100 °C at low strain rates in the sub-solvus window.
What is the maximum service temperature of Rene 95?
Rene 95 is rated for continuous use to about 650°C (1,202 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Rene 95 HIP+HT and Rene 95 AS-HIP?
HIP+HT is the default condition — standard supplied disk condition: fine ASTM 10–12 grain size for maximum tensile and low-cycle-fatigue strength to 650 °C. AS-HIP: pick for near-net HIP preforms where full disk-grade heat treatment is applied later, or for less critical hardware. Yield strength is 1,240 MPa in HIP+HT versus 1,120 MPa in AS-HIP.
