The addition of molybdenum and copper enhances their resistance to reducing acids, such as sulfuric acid. These bars are widely used in applications requiring durability and reliability under extreme conditions. Their mechanical properties make them suitable for both structural and pressure-containing components. They can withstand high temperatures without losing strength. Alloy 825 is known for its versatility across various industries.
The manufacturing process of Alloy 825 Round Bars involves precision casting and forging to ensure uniformity and high-quality finishes. The bars are then heat-treated to achieve the required mechanical properties, such as tensile strength and hardness. The surface is often polished to prevent corrosion and provide a smooth finish for industrial use. These bars are available in a wide range of diameters and lengths to meet specific application requirements. They can be easily machined, welded, and formed without compromising their integrity. Alloy 825 Round Bars maintain dimensional stability under thermal cycling. They are also resistant to stress corrosion cracking, making them reliable in challenging environments.
In terms of chemical composition, Alloy 825 Round Bars primarily consist of nickel, iron, and chromium. Nickel provides toughness and excellent corrosion resistance. Chromium enhances strength and protects against oxidation. Molybdenum improves resistance to pitting and crevice corrosion. Copper is added to boost resistance to strong reducing acids. Small amounts of titanium and aluminum may be present to stabilize the structure. The careful balance of these elements ensures the bars perform reliably across multiple industries. Their unique composition allows them to resist both oxidizing and reducing chemicals efficiently.
