Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
FDefault As fabricated | Standard stock condition for turbocharger wheels and small blades; γ′ forms on cooling so as-cast strength is already high. | 740 | 850 | 8 | 34 HRC | — |
Stress relieved | Choose when residual casting stresses or dendritic segregation must be reduced before machining of thin-wall parts. | 745 | 860 | 8 | 33 HRC | 1.3 % IACS |
Solution treated and aged | Use where a uniform, controlled γ′ size and best creep/rupture consistency are specified rather than the as-cast structure. | 780 | 900 | 6 | 36 HRC | 1.3 % IACS |
Hot isostatic pressed | Pick for fatigue-critical rotating parts: HIP closes interdendritic microporosity and markedly raises ductility and LCF life. | 780 | 910 | 10 | 35 HRC | 1.3 % IACS |

What is IN-713C?
IN-713C (N07713) is a γ'-precipitation-hardened cast nickel-base superalloy strengthened by roughly 6 % combined aluminium and titanium. It is chosen for good casting fluidity and low hot-tearing tendency in thin turbine sections, and is supplied as vacuum investment castings rated 740 MPa yield, 850 MPa tensile, 8 % elongation and 330 HB (34 HRC), usable to about 950 °C. It is a cast-only alloy and effectively non-weldable by fusion; machinability rates 10 of 100, so features are ground, EDM'd or ECM'd. IN-738LC is the usual step up where higher hot-corrosion resistance is required. IN-713C has a density of 7.91 g/cm³ (0.286 lb/in³), lighter than 89% of nickel alloy grades. It melts at 1,260°C (2,300 °F). IN-713C has a yield strength of 740 MPa (107 ksi) and a tensile strength of 850 MPa (123 ksi) — stronger than 82% of nickel alloy grades. Elongation at break is 8% and the elastic modulus is 205 GPa (29.7 Msi).

Working with IN-713C
Is IN-713C easy to machine?
Very difficult: rigid setups, ceramic or whisker-reinforced/coated carbide tools, low speeds with heavy positive rake and flood coolant; grinding, EDM and ECM are common for blade/wheel features.
Can IN-713C be welded?
Effectively non-weldable by fusion (≈6 % Al + Ti causes strain-age and liquation cracking); repairs use vacuum brazing or specialized low-heat-input laser/EB cladding with pre-/post-heat.
Can IN-713C be formed, bent or molded?
Cast-only alloy — vacuum investment casting with excellent fluidity and low hot-tearing tendency; HIP after casting to close interdendritic porosity for rotating parts.

IN-713C — frequently asked
What is IN-713C used for?
IN-713C is typically used for turbocharger turbine wheels, gas turbine blades and aerospace turbine vanes. In short: best-casting turbine superalloy; turbocharger wheel standard; cast only, non-weldable.
What is the yield strength of IN-713C?
IN-713C has a typical yield strength of 740 MPa (107 ksi) and a tensile strength of 850 MPa (123 ksi) — stronger than 82% of nickel alloy grades. Strength varies by condition: see the 4 listed tempers.
Is IN-713C easy to machine?
Not especially — machinability is rated not recommended (10/100, worse than 93% of nickel alloy grades). Very difficult: rigid setups, ceramic or whisker-reinforced/coated carbide tools, low speeds with heavy positive rake and flood coolant; grinding, EDM and ECM are common for blade/wheel features.
Can IN-713C be welded?
Not readily — weldability is rated not recommended (10/100). Effectively non-weldable by fusion (≈6 % Al + Ti causes strain-age and liquation cracking); repairs use vacuum brazing or specialized low-heat-input laser/EB cladding with pre-/post-heat.
What surface finishes work on IN-713C?
Grit blast plus chemical/abrasive-flow cleaning; hot-corrosion protection by pack/CVD aluminide or MCrAlY plus optional TBC; not anodizable, electroplating rarely used.
Can IN-713C be formed, bent or molded?
Cast-only alloy — vacuum investment casting with excellent fluidity and low hot-tearing tendency; HIP after casting to close interdendritic porosity for rotating parts.
What is the maximum service temperature of IN-713C?
IN-713C is rated for continuous use to about 950°C (1,742 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between IN-713C-F and IN-713C-STA?
F is the default condition — standard stock condition for turbocharger wheels and small blades; γ′ forms on cooling so as-cast strength is already high. STA: use where a uniform, controlled γ′ size and best creep/rupture consistency are specified rather than the as-cast structure. Yield strength is 740 MPa in F versus 780 MPa in STA.
