Neil Metals, Kolkata, India, is a trusted and reliable producer and supplier of **Hastelloy C276 Forgings**, providing corrosion-resistant high-performance parts for demanding industrial applications. Carefully engineered from superior-grade raw materials, the forgings are capable of withstanding the most severe chemical and thermal environments. With high manufacturing capabilities and strict quality assurance, Neil Metals supplies Hastelloy C276 forgings complying with international standards and for applications in **chemical processing, marine, pulp & paper, pollution control**, and **oil & gas**, providing superior strength, durability, and safety in service.
**Hastelloy C276 Forgings** (UNS N10276) consist of about **57% Nickel**, **15–17% Molybdenum**, **14.5–16.5% Chromium**, **4–7% Iron**, and **3–4.5% Tungsten**, with traces of Cobalt, Vanadium, and Manganese. These forged pieces provide **exceptional resistance** to a large array of corrosive media, such as **chlorides, highly oxidizing and reducing agents, wet chlorine gas, sulfuric, hydrochloric, and nitric acids**. Mechanical properties are **tensile strength of about 760–790 MPa**, **yield strength of about 300–350 MPa**, and **superb ductility and toughness**, even under harsh conditions of temperature and pressure.

**Hastelloy C276 Forgings** are widely utilized in the production of **valves, flanges, shafts, fittings, rings, discs, and specially shaped parts** for application in **chemical reactors, heat exchangers, scrubbers, pressure vessels, offshore platforms**, and **waste treatment plants**. Their enhanced resistance against **crevice corrosion, stress corrosion cracking, and pitting** positions them perfectly for applications in the presence of **acidic solutions, seawater, and oxidizing brines**. Forging enhances the grain structure of the alloy, leading to improved mechanical performance and fatigue life—making C276 forgings a reliable choice for mission-critical, highly corrosive applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
