What Is Incoloy 825 Round Bar?
Incoloy 825 Round Bar is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It is designed for industrial environments where resistance to corrosion, acids and localized attack is important.
The material is internationally identified as INCOLOY Alloy 825, UNS N08825 and W.Nr. 2.4858. Special Metals identifies Alloy 825 as a nickel-iron-chromium alloy with molybdenum and copper additions and lists round bar among its available product forms.
For international buyers, the same material may therefore appear under several different names:
| Common Name | International Designation |
|---|---|
| Incoloy 825 | Commercial alloy name |
| Incoloy Alloy 825 | Full alloy name |
| Alloy 825 | Alloy designation |
| UNS N08825 | UNS designation |
| N08825 | Short UNS reference |
| W.Nr. 2.4858 | Werkstoff number |
| 2.4858 | Short Werkstoff reference |
| Nickel-Iron-Chromium Alloy 825 | Material description |
Knowing these designations can make procurement easier when suppliers, drawings and international customers use different terminology.
Incoloy 825 International Names and Designations
A buyer searching for this material in India may use Incoloy 825 Round Bar, while an overseas engineering or purchasing department may specify Alloy 825, UNS N08825 or 2.4858.
These identifiers refer to the same alloy family:
- INCOLOY® Alloy 825
- Incoloy 825
- Alloy 825
- UNS N08825
- N08825
- W.Nr. 2.4858
- 2.4858 Nickel Alloy
Special Metals lists INCOLOY Alloy 825 as UNS N08825 / W.Nr. 2.4858.
This makes the international designation particularly useful when preparing RFQs for export orders, engineering projects or multinational procurement requirements.
Why Incoloy 825 Is Used in Corrosive Environments
Many industrial systems expose components to combinations of:
- Acids
- Chlorides
- High temperatures
- Reducing conditions
- Oxidizing conditions
- Moisture
- Process chemicals
In these environments, material selection becomes an important part of equipment reliability.
Incoloy 825 is engineered to provide strong resistance to both reducing and oxidizing acids. Special Metals specifically notes resistance to sulfuric and phosphoric acids, stress-corrosion cracking, pitting and crevice corrosion.
This makes the alloy relevant to applications where ordinary steels or less corrosion-resistant materials may not provide the required performance.
Key Properties of Incoloy 825
Resistance to Sulfuric and Phosphoric Acids
One of the important characteristics of Alloy 825 is its resistance to sulfuric and phosphoric acid environments. This is particularly relevant to chemical-processing applications.
Resistance to Localized Corrosion
The alloy provides resistance to localized forms of corrosion such as pitting and crevice corrosion. This characteristic can be important where stagnant or concentrated corrosive environments exist.
Stress-Corrosion Cracking Resistance
Incoloy 825 is also recognized for resistance to stress-corrosion cracking, making it suitable for selected process environments where mechanical stress and corrosive exposure occur together.
Resistance to Oxidizing and Reducing Conditions
Its alloying system provides useful resistance across both oxidizing and reducing chemical environments.
Fabrication and Welding
Special Metals reports that Alloy 825 has good weldability using conventional welding processes when appropriate procedures and filler materials are selected.
Chemical Composition of Incoloy 825
Published limiting composition information for Alloy 825 includes:
| Element | Composition |
|---|---|
| Nickel | 38.0–46.0% |
| Iron | 22.0% min. |
| Chromium | 19.5–23.5% |
| Molybdenum | 2.5–3.5% |
| Copper | 1.5–3.0% |
| Titanium | 0.6–1.2% |
| Carbon | 0.05% max. |
| Manganese | 1.0% max. |
| Silicon | 0.5% max. |
| Aluminium | 0.2% max. |
| Sulfur | 0.03% max. |
These are published limiting composition values; the applicable purchase specification and material test certificate should be used to verify the chemistry of supplied material.
Incoloy 825 Round Bar Specifications
For round bar procurement, the applicable standard should be clearly stated in the enquiry.
ASTM B425-26 covers nickel-iron-chromium-molybdenum-copper alloys including UNS N08825 in hot-finished and cold-drawn rounds, squares, hexagons and rectangles. The specification also addresses chemical and mechanical requirements.
| Parameter | Incoloy 825 Round Bar |
|---|---|
| Material | Incoloy 825 |
| Alloy | Alloy 825 |
| UNS | N08825 |
| Werkstoff | 2.4858 |
| Material Family | Nickel-Iron-Chromium Alloy |
| Product Form | Round Bar / Rod |
| Common Bar Standard | ASTM B425 |
| Available Conditions | As specified by purchase requirement |
| Documentation | As required by enquiry |
The required diameter, length, quantity, condition and applicable standard should always be confirmed before ordering.
Industrial Applications of Incoloy 825 Round Bar
Chemical Processing
Chemical plants can expose components to aggressive acids and corrosive process media. Incoloy 825 is used in selected chemical-processing equipment because of its resistance to several demanding chemical environments.
