Incoloy 825 round bar is a nickel-iron-chromium alloy that also contains copper, molybdenum, and titanium. Additionally in harsh chemical environments it provides exceptional corrosion resistance. While chromium adds oxidation resistance, the alloy's high nickel content guards against stress corrosion cracking. Molybdenum and copper improve resistance to reducing agents. With a tensile strength of up to 690 MPa and elongation of 45% it shows strong mechanical performance in tough conditions. Preston Pipes and Alloys provides Incoloy 825 bar, meeting ASTM B425 standards with a focus on precision and durability.
Alloy 825 round bar stands out for its strong resistance to acids like sulfuric and phosphoric, along with oxidizing agents and chloride-induced stress. It retains its mechanical strength and functions well at high temperatures. The material’s easy weldability makes it practical in many fabrication settings. Common uses of Incoloy 825 rod include chemical process equipment, marine exhaust systems, propeller shafts, sulphuric acid piping, and pickling tanks. Other applications include food and water hot vessels, ammonium sulphate vessels, and expansion bellows, showing how versatile the Incoloy 825 round bar really is.
The alloy 825 bar is made through hot rolling, cold drawing, forging and grinding. These processes enhance the bars' surface quality and give them shape. Tight tolerances and smooth finishes are facilitated by centerless grinding and peeling. Surface options include black, bright, polished and rough turned finishes. Typically, sizes fall between 14 and 300 mm in diameter and 1 and 6 meters in length. The bar is available in round, square, hex, and rectangle forms. Standards include ASTM B425 and ASME SB425, and custom sizes are also offered by suppliers.
Every Incoloy 825 round bar supplier and Incoloy 825 round bar stockist performs strict tests to ensure reliability. These include PMI, intergranular corrosion, ultrasonic, and magnetic particle testing. Mechanical tests check strength, ductility, and hardness. Additionally, bars undergo visual inspections to verify their precise dimensions and smooth surface. To prevent scratches and contamination during shipping, bars are wrapped in plastic film and placed in wooden or corrugated boxes. Depending on the size of the order and the destination, custom packaging is available. For bulk and custom orders, ask your supplier about the alloy 825 price per kilogram.
