UNS N06625 / 2.4856 /Inconel 625 Round Bar Nickel Alloy Rod Bright and Black Bars
Inconel 625 round bar (UNS N06625 / Werkstoff Nr. 2.4856) is a premium nickel-chromium-molybdenum alloy rod renowned for its exceptional strength, corrosion resistance, and thermal stability. Available as bright and black bars, it meets global standards including AMS 5837, ASTM B446, and DIN specifications, making it a top choice for high-demand industries worldwide .
Core Specifications & Dimensions
These nickel alloy rods offer versatile sizing to fit diverse applications:
- Diameter Range: 1.5 mm to 500 mm (0.0625″ to 20″), with bright bars typically ranging 4 mm–100 mm for precision uses .
- Length: 0.5 m to 6.0 m (1.6 ft to 19.7 ft), with custom cut lengths available.
- Tolerances: Cold-drawn bright bars feature tight tolerances (e.g., ±0.002″ for 0.0625″–0.1875″ dia), while hot-worked black bars follow H8–H13 or K9–K12 tolerances .
- Density: 8.44 g/cm³ (0.305 lb/in³), with a melting point of 1290–1350°C (2354–2462°F) .
Chemical Composition & Key Properties
The alloy’s performance stems from its precise chemistry (min. 58% nickel, 20–23% chromium, 8–10% molybdenum, 3.15–4.15% niobium) . This formulation delivers:
- Corrosion Resistance: Immunity to pitting, crevice corrosion, and chloride stress cracking—ideal for seawater, chemical processing, and nuclear applications . It resists dry chlorine up to 650°C and ammonia atmospheres .
- Mechanical Strength: Annealed bars exhibit tensile strength <1050 MPa (152 ksi), while cold-worked variants reach 1924 MPa (279 ksi) . High creep and rupture strength ensure reliability at 1093°C (2000°F) .
- Thermal Stability: Operates from cryogenic temperatures to 982°C (1800°F), with oxidation resistance in carburizing/nitriding environments .
Bright vs. Black Bars: Key Differences
Applications Across Industries
Inconel 625 round bars excel in harsh environments:
- Aerospace: Engine exhaust systems, thrust reversers, and turbine shroud rings, leveraging high fatigue strength .
- Marine: Mooring cables, propeller blades, and undersea communication cable sheathing, resisting seawater corrosion .
- Chemical Processing: Reaction vessels, distillation columns, and heat exchangers, enduring acidic and chloride-rich media .
- Nuclear: Reactor-core components and control rods, with exceptional corrosion resistance in high-purity water .
- Oil & Gas: Downhole tubing and valves, withstands sour gas and extreme pressures .
Quality Assurance
All bars undergo rigorous testing:
- Destructive tests (tensile, hardness) and non-destructive tests (ultrasonic, dye penetrant) .
- Annealed at 1038°C (1900°F) for optimal ductility .
- Compliance with NACE MR 0175 and ISO 15156-3 for sour service .
Equivalent grades include JIS NCF 625, BS NA 21, and AFNOR NC22DNB4M , ensuring global compatibility.
