Neil Metals, situated in Kolkata, India, is a reliable manufacturer and supplier of **Hastelloy Forgings**, providing high-quality corrosion-resistant alloy components for critical industrial applications. Well known for accuracy in engineering and rigorous quality control, Neil Metals manufactures Hastelloy forgings that conform to international standards for strength, durability, and corrosion resistance. These forged items are well suited for applications like **chemical processing, marine, petrochemical, power generation**, and **pharmaceuticals**, where hostile environments demand materials with superior mechanical integrity and long life.
**Hastelloy Forgings** come in several grades like **C-276, C-22, B-3, C-2000, and X**, each of which is custom-designed for particular corrosion problems. Commonly made up of **Nickel (55–70%)**, **Molybdenum (up to 30%)**, **Chromium (up to 23%)**, and others such as **Iron, Tungsten, and Cobalt**, the alloys provide excellent resistance to **oxidizing and reducing media**, **chlorides**, **acids**, and **stress corrosion cracking**. Forging gives the material a refined grain structure that makes it stronger mechanically, more impact resistant, and **fatigue-resistant at high pressure and temperature**.

**Hastelloy Forgings** are utilized to produce a broad variety of essential parts such as **flanges, shafts, rings, valve bodies, nozzles, bushings, connectors**, and **custom shapes**. These components are crucial in **heat exchangers, chemical reactors, scrubbers, offshore platforms**, and **waste treatment facilities** where harsh corrosion, temperature variation, and mechanical load occur. Because of their superior formability, weldability, and resistance to thermal stress, Hastelloy forgings are a design engineer’s and fabricator’s material of choice for creating systems that must operate in severe and corrosive service environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
