Inconel 625 Nickel Alloy Round Bar EN 2.4856 Rod Custom Cutting in Length Bright NFC625 Shaft
Inconel 625 (UNS N06625, EN 2.4856, also known as NFC625) is a premium nickel-chromium-molybdenum alloy renowned for its exceptional corrosion resistance, high-temperature strength, and excellent fabricability. The round bar/rod form of this alloy is widely utilized in critical industrial applications where durability and performance under harsh conditions are non-negotiable. Below is a comprehensive overview of its key attributes, supporting services, and related products.
1. Chemical Composition
The superior performance of Inconel 625 stems from its precisely balanced chemical composition, which imparts resistance to corrosion (including pitting, crevice corrosion, and stress corrosion cracking) and maintains strength at elevated temperatures. The typical composition (by weight, % max unless specified) adheres to international standards such as ASTM B446/B446M and EN 10088-1:
| Element | Content Range (%) | Primary Function |
|---|---|---|
| Nickel (Ni) | 58.0 min | Base metal; provides fundamental corrosion resistance and alloy stability. |
| Chromium (Cr) | 20.0 - 23.0 | Enhances oxidation resistance at high temperatures and resistance to acidic media. |
| Molybdenum (Mo) | 8.0 - 10.0 | Boosts resistance to pitting/crevice corrosion (especially in chloride environments). |
| Niobium (Nb) + Tantalum (Ta) | 3.15 - 4.15 | Forms precipitates (e.g., Ni₃Nb) to strengthen the alloy without heat treatment. |
| Iron (Fe) | 5.0 max | Improves fabricability while minimizing impact on corrosion resistance. |
| Carbon (C) | 0.10 max | Controlled to reduce carbide precipitation (avoids intergranular corrosion). |
| Manganese (Mn) | 0.50 max | Aids in deoxidation during manufacturing; low content prevents brittleness. |
| Silicon (Si) | 0.50 max | Enhances fluidity during casting; controlled to avoid oxide inclusions. |
| Phosphorus (P) | 0.015 max | Minimized to prevent brittleness and intergranular corrosion. |
| Sulfur (S) | 0.015 max | Strictly limited to improve weldability and reduce hot cracking risk. |
2. Mechanical Properties
Inconel 625 round bars exhibit outstanding mechanical strength—both at room temperature and high temperatures (up to 1,093°C/2,000°F)—without relying on heat treatment (it achieves strength through cold working or solid-solution strengthening). The following values are typical for annealed round bars (per ASTM B446/B446M), with variations based on bar diameter and cold-working degree:
| Property | Test Condition | Typical Value | Unit |
|---|---|---|---|
| Tensile Strength (UTS) | Room Temperature | 827 - 965 | MPa |
| Yield Strength (0.2% offset) | Room Temperature | 414 - 551 | MPa |
| Elongation at Break | Room Temperature (2in gauge) | 30 - 40 | % |
| Hardness (Rockwell B) | Room Temperature | 80 - 95 | HRB |
| Tensile Strength (UTS) | At 650°C (1,200°F) | 551 - 620 | MPa |
| Yield Strength (0.2% offset) | At 650°C (1,200°F) | 310 - 379 | MPa |
Key Advantage: The alloy retains over 60% of its room-temperature strength at 650°C, making it ideal for high-heat applications like gas turbine components.
3. Equivalent / (Similar Grades)
Inconel 625 is standardized globally under different designations, ensuring consistency across industries and regions. The most common equivalent grades are:
| Standard/Region | Grade Designation | Key Application Match |
|---|---|---|
| ASTM (USA) | UNS N06625 | Aerospace, chemical processing |
| EN (Europe) | EN 2.4856 | Oil & gas, marine engineering |
| AMS (Aerospace, USA) | AMS 5666, AMS 5837 | Aircraft engine parts, rocket components |
| DIN (Germany) | W. Nr. 2.4856 | Industrial furnaces, heat exchangers |
| JIS (Japan) | NCF 625 | Petrochemical, power generation |
| GB (China) | NS336 | Chemical equipment, offshore structures |
4. Custom Cutting Service for Round Bars
To meet diverse project requirements, we offer precision custom cutting for Inconel 625 round bars (EN 2.4856 rods/NFC625 shafts), with the following capabilities:
- Cutting Methods: Utilizes advanced CNC sawing, laser cutting, and waterjet cutting to ensure clean, burr-free edges and minimal material waste.
- Length Customization: Supports both small and large orders, with length ranges from 50mm (2in) to 6,000mm (20ft). Tolerances as tight as ±0.1mm are available for high-precision applications (e.g., aerospace shafts).
- Surface Finish: The "Bright" finish option (as referenced in the title) features a smooth, polished surface (Ra ≤ 0.8μm) that reduces friction, resists contamination, and eliminates the need for additional post-processing in critical assemblies.
- Quality Assurance: Each cut bar undergoes dimensional inspection (via calipers or laser measurement) and surface quality checks to comply with ASTM B446/B446M and customer specifications.
5. Applications
Inconel 625 round bars/rods are trusted in industries where failure is costly or dangerous, thanks to their corrosion and high-temperature resistance. Key applications include:
- Aerospace & Defense: Engine shafts, turbine blades, fasteners, and rocket motor casings (resists high heat and fuel corrosion).
- Oil & Gas: Downhole drill collars, wellhead components, and subsea pipelines (withstands sour gas, saltwater, and high pressure).
- Chemical Processing: Heat exchanger tubes, reactor vessels, and pump shafts (resists acids like sulfuric acid, hydrochloric acid, and acetic acid).
- Power Generation: Boiler tubes, steam turbine components, and nuclear reactor parts (maintains strength under high pressure and temperature).
- Marine Engineering: Propeller shafts, seawater valves, and offshore platform hardware (resists seawater corrosion and biofouling).
- Medical Devices: Surgical instruments and implantable components (biocompatible and resistant to bodily fluids).
6. Other Inconel 625 Products
Beyond round bars/rods, Inconel 625 is available in a full range of forms to support end-to-end manufacturing needs:
- Sheet & Plate: Used for pressure vessels, heat exchanger shells, and structural components (thickness: 0.5mm - 100mm).
- Tube & Pipe: Seamless and welded tubes for fluid transport in chemical and power industries (OD: 6mm - 219mm).
- Wire & Wire Mesh: For high-temperature gaskets, filters, and electrical components (wire diameter: 0.1mm - 5mm).
- Fasteners: Bolts, nuts, washers, and studs (compliant with ASTM F468) for critical joints in aerospace and oil & gas.
- Forgings: Custom forgings (e.g., valve bodies, turbine disks) for high-stress applications requiring uniform grain structure.
- Welding Consumables: Wires (ERNiCrMo-3) and electrodes (ENiCrMo-3) for joining Inconel 625 components while maintaining corrosion resistance.
