Inconel 751 Mechanical Properties
UNS N07751 is a nickel-based superalloy known for its impressive mechanical properties. Its great strength and good fracture toughness makes it an ideal choice for many extreme conditions, such as high temperature applications and hostile environments. It can also be used to parts with high fatigue resistances, making it a popular choice in the aerospace industry. While these mechanical properties make Inconel 751 suitable for many situations, it is important to consider the alloy’s low ductility before applying it in certain situations.
Properties | Metric | Imperial |
---|---|---|
Tensile Strength (precipitation hardened, value at room temperature) | 1275 MPa | 184900 psi |
Yield strength (at strain 200%, precipitation hardened, value at room temperature) | 875 MPa | 127000 psi |
Elongation at break (precipitation hardened) | 25% | 25% |
The most important physical property of Inconel 751 is its high melting point – it can withstand temperatures up to 2200°F without losing structural integrity. It also has good electrical conductivity and thermal conductivity. The alloy has a low coefficient of thermal expansion which makes it ideal for use in applications where temperature changes are a factor.
