Never heard of Hastelloy? Well, it is the trademark name of Haynes International, Inc, for a series of high-strength, nickel based, corrosion resistant alloys.  Hastelloys are commonly used by the chemical processing industries and have many applications.

The Hastelloy trademark is applied as the prefix name to about twenty two different metal alloys loosely grouped by the metallurgical industry under the material term “superalloys” or “high performance alloys”. These ”superalloys” are totally resistant to pitting, stress-corrosion cracking and to oxidizing atmospheres up to 1900 F.

The predominant element in all the alloys is the transition metal nickel. Other alloying ingredients are added to nickel in each trademark designation subcategory and include varying percentages of the elements: molybdenum,carbon, chromium, iron,cobalt, copper,titanium, manganese, zirconium, aluminum and tungsten.

So you can already guess that this product is of great use in the motoring world. Hastelloy X, for instance, is a nickel-chromium-iron-molybdenum alloy which possesses a combination of oxidation resistance and high temperature strength. It is widely used in gas turbine engines for combustion zone components such as transition ducts, combustor cans, spray bars, flame holders and also in afterburners, tailpipes and cabin heaters. It also has wide use in industrial furnace applications, its unusual resistance to oxidizing, reducing and neutral atmospheres makes it an ideal material in these types of extreme environments.

Hastelloy is generally available in cast and wrought forms. Sometimes it can even be found as a powder metallurgy(PM) product. Conventional PM processing of Hastelloy X includes press and sinter that results in compacts that are limited to simple geometric shapes such as cylinders, which are not fully dense. Additional processing, like hot isostatic pressing (HIP), can achieve nearly 100 percent theoretical density.

Hastelloy machining has penetrated a number of industries, such as: medical, fluid and gas handling, military, electronic, measurement producing fittings, adapters, connectors, housings, stems, outlets, inlets, pins, manifolds, sleeves, nuts, screws and studs. This technology allows for stronger, more resistant, components and is sure to be an advantageous one in the motoring world, helping to drive performance to new frontiers.
