Overview

Our Inconel 625 alloy round bars represent the pinnacle of nickel-chromium-based superalloy performance. Renowned for its exceptional strength, outstanding corrosion resistance, and superb fabricability, Inconel 625 is the material of choice for the most demanding applications across aerospace, marine, chemical processing, and oil & gas industries. We supply precision-crafted round bars in a comprehensive size range from 6mm to 300mm diameter, available in both Bright (cold drawn and polished) and Black (hot finished) surface conditions to meet your specific machining and application requirements.

Key Properties & Advantages

• Excellent Corrosion Resistance: Highly resistant to a wide range of severe corrosive environments, including pitting, crevice corrosion, and chloride-ion stress-corrosion cracking.

• High Strength: Exceptional yield, tensile, and creep-rupture strength, maintained at elevated temperatures up to 1000°C (1800°F).

• Oxidation Resistance: Forms a stable, protective oxide layer that provides excellent resistance to oxidation and carburization in high-temperature service.

• Ease of Fabrication: Can be readily welded and fabricated using standard techniques, making it versatile for complex component manufacturing.

Available Specifications

• Product Form: Round Bars

• Diameter Range: 6 mm (0.236") to 300 mm (11.81")

• Length: Random mill lengths or cut-to-size.

• Surface Finish:

  • Bright Bars (Cold Drawn & Polished): Smooth surface finish, close dimensional tolerances, ideal for precision machining and applications where aesthetics are important.

  • Black Bars (Hot Finished): A scaled surface resulting from hot rolling, typically used for general applications where surface finish is not critical, often offering cost savings.

Applications

Inconel 625 round bars are extensively used in critical components for:

• Aerospace: Engine exhaust systems, thrust reversers, ducting systems.

• Marine Engineering: Propeller blades, submarine auxiliary propulsion motors, seawater piping.

• Chemical Processing: Reactors, heat exchangers, distillation columns, piping systems.

• Oil & Gas: Downhole and surface equipment, wellhead components, gas separation systems.

• Nuclear Power: Control rod components, core catcher material.

• Pollution Control: Flue gas desulfurization systems, scrubbers.

Quality Assurance

All materials are supplied with full traceability and mill test certificates (MTC) to EN 10204 3.1 or equivalent standards, ensuring they meet the stringent chemical and mechanical property requirements of the specified grades.
