Incoloy 825 round bars are high-performance nickel-iron-chromium alloys known for their excellent resistance to corrosion and oxidation, making them ideal for demanding applications in various industries. As a B2B buyer, concerns often revolve around material selection, specifications, and supplier reliability. This article will guide you through the essential aspects of inconel 825 round bars, helping you make informed purchasing decisions.
Key Specifications to Consider for Incoloy 825 Round Bar
Understanding the key specifications of Incoloy 825 round bars is vital for ensuring they meet your project demands. Here are several important specifications to consider:
Chemical Composition: Incoloy 825 typically contains nickel (38-46%), chromium (19.5-23.5%), iron (balance), and small amounts of molybdenum, copper, and titanium. This composition provides excellent resistance to pitting and stress corrosion cracking.
Mechanical Properties: The tensile strength and yield strength of Incoloy 825 are important for applications that require high strength under pressure. The alloy typically exhibits a tensile strength of around 620 MPa and a yield strength of approximately 310 MPa at room temperature.
Dimensions and Tolerances: Ensure that the round bars meet the required diameters and tolerances for your application. Common diameters can range from 1/16 inch to several inches, depending on the supplier's capabilities.
Surface Finish: The surface finish can affect the performance of the round bars, particularly in corrosive environments. Specify whether you require a polished finish or a standard mill finish.
Standards and Certifications: Verify that the products are manufactured according to relevant standards, such as ASTM B425, and that they have the necessary certifications, such as ISO9001 or AS9100.
