Neil Metals, a Kolkata, India-based company, is a reputed maker and supplier of **Incoloy 825 Forgings**, supplying high-grade corrosion-resistant parts for extremely demanding industrial uses. With their accuracy in production, metallurgical skills, and compliance with global quality standards, Neil Metals are making Incoloy 825 forgings that yield superior performance under oxidizing as well as reducing conditions. These forgings are suitable for critical applications in the **chemical processing, oil & gas, marine, pollution control, and power generation** industries, providing long-term reliability, mechanical properties, and corrosion resistance.
**Incoloy 825 Forgings** (UNS N08825) are nickel-iron-chromium alloyed with additions of **Molybdenum (2.5–3.5%)**, **Copper (1.5–3%)**, and **Titanium (0.6–1.2%)**, which improve their ability to resist all types of corrosion. With a standard composition of **38–46% Nickel**, **19.5–23.5% Chromium**, and **balance Iron**, the forgings are highly resistant to **sulfuric acid, phosphoric acid, nitric acid, and chlorides**. The mechanical properties comprise **tensile strength of \~585 MPa**, **yield strength of \~220 MPa**, and **elongation up to 30–45%**, providing stability against thermal and chemical stress.

**Incoloy 825 Forgings** find extensive application in the production of **flanges, shafts, rings, nozzles, valve bodies, and custom-machined components** for applications in **acidic environments, seawater, and chemical contaminants**. Some of the typical applications are **heat exchangers, evaporators, pickling tanks, marine exhaust systems, chemical reactors**, and **nuclear fuel reprocessing equipment**. The stress corrosion cracking and localized corrosion resistance of the alloy renders it a reliable option for use in **offshore oil rigs, pollution control equipment**, and **chemical recovery systems**. Incoloy 825 forgings exhibit enhanced performance, ease of handling, and extended service life even in extreme industrial conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
