Inconel Nickel Alloys

Inconel is a nickel-chromium alloy that is classified as a superalloy because of its high-performance qualities and resistance to corrosion and oxidation. It performs well in both low and high temperature applications where other materials such as steel and aluminum would fail, and is also resistance to pitting, corrosion cracking and crevice.

Nickel Alloy Inconel for High Temperature Applications

Magellan Metals offers several grades of Inconel nickel alloys that are available in a wide range of formats including wire, plate, sheet, pipe fittings, bar, flanges, and more. View the individual product pages below for more information about the chemical analysis, available formats and applications for each grade of Inconel nickel alloy.

What is the Difference Between Hastelloy and Inconel?

Both Hastelloy and Inconel are superalloys that provide high corrosion resistance and durability. They cost more than stainless steel but because of their reliable performance in harsh environments, nickel alloys are preferred for demanding applications such as geothermal., nuclear, aerospace, and others.

Chemical Properties of Inconel vs. Hastelloy Nickel Alloys

Inconel is a nickel-chromium alloy that forms a passivating oxide layer when it is heated, making it resistant to extreme heat and corrosion, as well as pressure and oxidation. It chemical composition also give Inconel superior resistance to sodium chloride at a wide range of temperatures, making it an ideal choice for marine applications or those involving constant exposure to salt and saltwater.

Depending on the grade, Hastelloy is a nickel-molybdenum or nickel-chromium-molybdenum alloy that performs well at high temperatures and is easily fabricated and formed, making it suitable for either cold working or welding applications. Because it works well in highly corrosive environments and resists oxidation, Hastelloy is commonly used for chemical processing applications.

What is the Melting Point of Inconel vs. Hastelloy?

Inconel has a higher melting point of 2,540°F-2,600°F (1,390°C-1,425°C), where Hastelloy has a melting point of 2,410-2,460°F (1,320°C-1,350°C). Nickel alloys begin to lose their tensile strength before they reach melting point, so it is generally recommended that application temperatures are kept well below these ranges.

Applications for Inconel and Hastelloy Nickel Alloys

Both Inconel and Hastelloy provide corrosion-resistant properties and excellent fatigue strength for demanding industrial applications. They are used by many of the same industries including aircraft, marine, chemical processing applications and others, but their chemical composition and resistance to temperature make each of these nickel alloys ideal for specific applications.

Inconel has a high melting point, provides resistance to corrosion and oxidation and performs well at high temperatures. It is used for a range of applications, including:

  • Aerospace
  • Power generation
  • Nuclear reactors
  • Gas turbines
  • Pressure vessels

Hastelloy has a lower melting point that Inconel, but it carries higher tensile strength in high temperature and corrosive environments. Nickel alloy Hastelloy is used by industries such as:

  • Pollution control
  • Waste treatment
  • Paper processing
  • Chemical processing
