Mechanical Properties of ASME SB 409 UNS N08810 Plates:
1. Tensile Strength: The tensile strength of ASME SB 409 UNS N08810 plates typically ranges from 75,000 psi (517 MPa) to 105,000 psi (724 MPa). This high tensile strength makes the alloy suitable for applications where mechanical strength is essential.
2. Yield Strength: The yield strength of these ASTM B409 Incoloy 800H is approximately 30,000 psi (205 MPa) at room temperature. This is the stress at which the material begins to deform plastically.
3. Elongation: Nickel Incoloy 800H plates generally exhibit an elongation of around 30% to 35%. This indicates the ability of the material to deform before failure under tensile loading.
4. Hardness: The Incoloy alloy 800H has a typical hardness value of 150 to 210 Brinell (HB), depending on factors like heat treatment and plate thickness. The hardness can be adjusted through heat treatment processes.
5. Modulus of Elasticity: The modulus of elasticity (Young's modulus) for the ASME SB 409 UNS N08810 plate sheet is approximately 28.5 x 10^6 psi (196 GPa). This property characterizes the material's stiffness and its ability to return to its original shape after deformation.
6. Impact Strength: The impact strength of ASTM B409 UNS N08810 plates can vary depending on factors like temperature and plate thickness. Generally, it exhibits good impact resistance at both room temperature and elevated temperatures.
7. Creep Resistance: Incoloy 800H UNS N08810 is known for its excellent creep resistance, making it suitable for use in high-temperature applications where the material is subjected to prolonged stress at elevated temperatures.
8. Fatigue Resistance: The nickel alloy 800h hot drawn plate sheet exhibits good fatigue resistance, which is crucial for applications involving cyclic loading and thermal cycling.
It's important to note that the mechanical properties of ASME SB 409 UNS N08810 plates can vary depending on factors such as heat treatment, plate thickness, and testing conditions. Therefore, it's advisable to refer to the specific material certifications and manufacturer's data for precise mechanical property values for your application.
