If you are looking for sheets of UNS N08825, ASTM B423 or alloy 825 assets tier, Mehta Metals is here to help you collect sharpness, reliance and high-quality supplies. In this composition we will provide the chemical composition of UNS N08825, Incoloy 825 features and the difference from ASTM B424 vs. B423 and the leading way to acquire these nickel-iron-chromium sheets for industrial use.
Introduction to UNS N08825 / Alloy 825
UNS N08825 is commonly called the alloy 825 or Incoloy 825. It is a nickel-iron-chromium-nickel alloy that has been amplified with molybdenum copper and titanium. Due to this combination it has a high resistance to corrosion (oxidizing and reducing chloride environments) which makes it an ideal choice for petroleum, chemical and oil & gas as well as different industries that require heavy resources.
When firms are reviewing for Nickel-Iron-Chromium alloy sheet or sheets UNS N08825 typically, they are seeking out resources that will be used in radical acrid or chemical rules. We offer quality assured sheets and plates of this alloy tier for influential applications.
Chemical Composition of ASTM B423 UNS N08825
As per the standard ASTM B423 that covers open pipe as well as tube forms in UNS N08825, chemical composition is determined in the following manner:
| Element | Composition Range |
| Nickel (Ni) | 38.0 % to 46.0 % |
| Chromium (Cr) | 19.5 % to 23.5 % |
| Iron (Fe) | Minimum 22.0 % |
| Molybdenum (Mo) | 2.5 % to 3.5 % |
| Copper (Cu) | 1.5 % to 3.0 % |
| Titanium (Ti) | 0.6 % to 1.2 % |
| Carbon (C) | ≤ 0.05 % |
| Manganese (Mn) | ≤ 1.0 % |
| Silicon (Si) | ≤ 0.5 % |
| Sulfur (S) | ≤ 0.03 % |
| Aluminum (Al) | ≤ 0.2 % |
On top of that, identified elements such as manganese, sulfur, and silicon are controlled to very low stages to forbid degradation of their components, uniquely in environments that are corrosive.
It is influential to remember it is the case in the case of ASTM B424 (which includes sheets, plates and strips) identical compositions of the ASTM B424 are used to UNS N08825 that is rolled in sheets or plates.
So, regardless of whether you pick up UNS N08825 as a form of a sheet or pipe or tube form the chemical composition is in line with these suggestions.
Mechanical Aspects & In

Incoloy 825 Components
To superior understand the advantages of Incoloy 825’s material quality Here are the general mechanical aspects of the material under ordinary (annealed) situations:
- Tensile wealth (minimum): 85 ksi ( 586 MPa)
- Yield property (0.2 percent offs50 millimeters): 30%
These standards are suitable for both the sheet (ASTM B424)) as well as tube (ASTM B4223) forms that are annealed in condition.
Second characteristics in Incoloy 825 are:
- Outstanding resistance to corrosion both in reducing and oxidizing environments (e.g. sulfuric, phosphoric and phosphoric acids)
- Resistance to chloride stress corrosion cracking, pitting along with Crevice corrosion
- Stability and weldability are amazing Notably when titanium is employed as a stabilizer to eliminate intergranular corrosion
- Ductility across an extensive temperature range, from cold through several hundred degrees Celsius
- Due to this combination of durability, asset, resistance to corrosion and resilience, Alloy 825 is a prime choice in industrial settings that require a lot of effort.
ASTM B423 vs ASTM B424 — What’s the Difference?
Since you’ve asked regarding ASTM B424 and B423, here’s a compact comparison:
- ASTM B423 covers expansive pipe and tube forms of Nickel-Iron-Chromium-Molybdenum-Copper alloys (UNS N08825, N08221).
- ASTM B424 covers sheets, plates, and strips developed from identical alloy grades (N08825 N08221).
In short, B423 stands for tubular forms. B424 is designed for flat forms. Mechanically and chemically the alloy that is used for tubular forms is identical. So if you obtain UNS N08825 sheets that are ASTM B424, you will acquire the same alloy elements similar to the B423 tube we supply.
If buyers are comparing the prices as well as capabilities, it’s ready for use to indicate which type of format (sheet sheet, strip, plate, tube) and the standard (B424 or B423) they need.
Why Industries Choose UNS N08825 Sheets & Alloy 825
Industries that cover chemical processing, oil and gas marine, electricity generation and nuclear industries often require elements that are gifted to withstand harsh locales that are corrosive. UNS N08825 sheets provide the following advantages:
- Leading resistance to both reducing and oxidizing acids
- Strong resistance to stress caused by chloride corrosion
- Outstanding mechanical capital, ductility and mechanical resource
- Long-lasting service life steady under heightened temperatures, cyclical and radical chemical limitations
With these advantages numerous applications rely upon UNS N08825 sheets or plates instead of using cheap stainless steels or weaker alloys.
Sample Use Cases & Applications
Here are a few credible-world instances in which the UNS N08825 (Alloy 825) is positive:
- Processing vessels and acid pickling vessels
- Chemical method heat exchangers for heat
- Tubing for gas and oil, or piping exposed to view or hydrochloric acid
- Systems for marine exhaust or seawater handling
- Control equipment for pollution and scrubbers for flue gas
- Reprocessing of nuclear fuels or radioactive material handling
In every case use of correct specifications ASTM B424 sheets or ASTM B423 tubes can result in higher-quality durability and lower maintenance costs.
