Custom Exotic Alloy Forgings

exotic alloy forgings


R&M Forge and Fittings manufactures forged exotic alloy parts for a wide range of industries and applications. Our exotic alloy capabilities include Inconel, Hastelloy, and Haynes.


Exotic Alloys (Superalloys)

Exotic alloys or superalloys are materials that have a high concentration of specific metallics and are known for their resistance to high temperatures and stress. These enhanced alloys have excellent performance properties including extreme durability, strength, corrosion resistance, and more. Exotic alloys are made for demanding working conditions that are commonly found in industries such as industrial, automotive, marine, and petrochemical. These materials share several properties with our Nickel Alloys

Benefits of Inconel

Inconel is a family of nickel-based superalloys that are popular for their ability to withstand extreme conditions. When heated, Inconel alloys form a stable, thick oxidized layer that protects the surface from future uniform attacks. Compared to other materials like Duplex, Inconel alloys are very resistant to corrosion and oxidation while retaining strength in extreme hot or cold temperatures. These superalloys are relatively easy to fabricate and the iron content makes them a more cost-effective solution for numerous applications. These materials are also resistant to brine, seawater, chloride, and sour gar that are ideal for gas and oil industries. Types of Inconel include:

  • Inconel Alloy 625 (UNS N06625): Avid resistant, great weldability
  • Inconel Alloy 718 (UNS N07718): Great weldability and gamma double prime strength
  • Inconel Alloy X-750 (UNS N07750): Increased aluminum content to improve rupture strength 

Benefits of Hastelloy

Hastelloy is a nickel molybdenum alloy that has similar characteristics to Inconel, such as superior corrosion resistance and high resistance to uniform attacks. Although all grades of Hastelloy alloys share these properties, certain grades are optimized for specific purposes. During high temperatures, Hastelloy becomes stronger and harder making it great for welding applications. This metal can be forged and cold-worked due to its high ductility. Unlike other materials like Duplex, Hastelloy alloys hold an outstanding resistance to oxidizing, reducing agents, and are a great choice for chemical processing and petrochemical industries.

  • Hastelloy Alloy C-276 (UNS N10276): highly resistant to localized corrosion attacks and aggressive corrosion
  • Haynes 230 (UNS N06230): premier resistance to nitriding environments
  • Hastelloy C-22 (UNS N06022): enhanced resistance to crevice corrosion, pitting, and stress cracking
  • Hastelloy X (UNS N06002): oxidation resistance with operating temps up to up to 2200°F
