In this blog post, we’re going to look at three distinct types of exotic alloys and how they’re used in the world of alloy rolled ring forging.

HASTELLOY X

This is a nickel/chromium/iron/molybdenum alloy which is both resistant to oxidation and elevated temperatures. It is easy to fabricate and offers good ductility after extended exposures to temperatures up to 1600 degrees Fahrenheit (870 degrees Celsius) for 16,000 hours.

Hastelloy X is used in gas-turbine engines for combustion zone parts such as transition ducts, spray bars, combustor cans and flame holders. You’ll also find it in industrial furnaces and in the chemical industry for muffles, retorts and furnace baffles.

It is forged between 2225 degrees Fahrenheit (1215 degrees Celsius) and 1550 degrees Fahrenheit (840 degrees Celsius).

Inconel

Inconel is a family of austenitic nickel/chromium superalloys.

These alloys are resistant to oxidation and can maintain their structural integrity in the face of excessive temperatures. They are used in applications that require materials that succumb to caustic corrosion or corrosion caused by high purity water and stress-corrosion cracking.

It is used in several industries, including aerospace, food processing, chemical processing, and in making jet engine parts, commercial gas turbines and cryogenic storage tanks.

Waspaloy

First developed in 1958, Waspaloy is an age-hardening nickel-based superalloy with useful strength at temperatures up to 1800 degrees Fahrenheit/980 degrees Celsius.

It is difficult to weld, and performs best on material in a solution-annealed conditions. It has good corrosion resistance, and is relatively impervious to oxidation in gas turbine engine atmospheres, making it useful for operating in extreme environments.

You’ll find it working in gas turbine blades, seals, rings, shafts and turbine disks.
