ASTM B424 is a specification that covers the requirements for nickel-iron-chromium-molybdenum-copper alloy plates, sheets, and strips, which are commonly known as Incoloy 825. Here are some of the key mechanical properties specified by ASTM B424 UNS N08825 (Incoloy 825) material:
1. Tensile Strength: The minimum tensile strength of Incoloy 825 plates, sheets, and strips per ASTM B424 is typically 85,000 psi (586 MPa). This is the maximum stress the material can withstand when subjected to a tensile load.
2. Yield Strength: The minimum yield strength of ASTM B424 UNS N08825 plates, sheets, and strips per ASTM B424 is typically 30,000 psi (205 MPa). This is the stress at which the material begins to deform plastically.
3. Elongation: The minimum elongation for Incoloy alloy 825 plates, sheets, and strips is typically 30%. Elongation represents the material's ability to stretch without breaking and is expressed as a percentage of the original length.
4. Hardness: ASME SB424 UNS N08825 typically has a hardness of approximately 85 HRB (Rockwell B scale) or 160 HB (Brinell hardness).
