Quantity
The UNS N08825 Nut is manufactured from NiCr21Mo alloy, offering excellent resistance to stress corrosion cracking. Available in standards such as DIN, NF, ANSI, and BSW, it comes in a size of M39*3 with a hardness not exceeding 200 HB, ensuring stable performance at temperatures up to 550°C. Its outstanding corrosion resistance and mechanical strength make it a top performer in industries such as chemicals, petroleum, natural gas, and high-temperature applications. Whether facing highly corrosive media or continuous high-temperature challenges, the UNS N08825 Nut provides reliable connection assurance, meeting the stringent demands of industrial applications for high-performance fasteners.
The physical properties of Incoloy 825, a nickel-based alloy, are integral to its material characteristics, including density, melting point, thermal expansion coefficient, and thermal conductivity. These properties directly influence the material's thermodynamic behavior, machinability, and application scope. The UNS N08825 Nut is precisely engineered from this high-performance material, providing reliable solutions for fastening needs in extreme environments.
1. Density: 8.14 g/cm³
Density refers to the mass per unit volume of a material and is a critical physical parameter for assessing mass distribution. The relatively high density of the UNS N08825 Nut indicates substantial mass, making it suitable for heavy-duty structural components requiring high strength and corrosion resistance, such as petrochemical equipment and nuclear reactor parts.
