HAYNES® 230® alloy
Catalyst grid supports, gas turbine components, high temperature bellows, furnace components.
HAYNES® 230® alloy is a nickel-chromium-tungsten-molybdenum alloy which combines excellent high temperature strength and oxidation resistance with superior long term stability and good fabricability. It has lower thermal expansion characteristics than most high temperature alloys and resists grain coarsening with prolonged high temperature exposure.

Additional Information on HAYNES® 230® alloy
HAYNES® 230® alloy is one of the many Nickel-based alloys that Elgiloy provides for its customers. It is absolutely one of the premium alloys on the market and can be used in a wide variety of industries for a number of different types of machinery. As one of the most flexible and reliable alloys out there, it can be trusted to perform the way you want it to over very long periods of time, all while maintaining the same properties that you have come to expect from other Nickel alloys. This is why many professionals today continue to use HAYNES® 230® alloy in the building and maintaining of their machines.
As a nickel-chromium-tungsten-molybdenum alloy, HAYNES® 230® alloy strip has some of the same characteristics that you have come to expect from similar alloys in the market. These characteristics include high temperature resistance and resistance to oxidation. In fact, HAYNES® 230® alloy strip has been known to resist oxidation where temperatures get to over 2000 degrees, which is among the best of any alloys on the market today. It is also resistant to grain coarsening in high temperatures and exhibits lower thermal expansion characteristics than other alloys made specifically to withstand high temperatures.
Furthermore, HAYNES® 230® alloy is very easily fabricated at room temperature. This allows for ease in welding and forming the alloy to meet your specific requirements. It can be formed by both hot and cold working, adding to the already impressive amounts of flexibility that HAYNES® 230® alloy strip has over similar alloys. However, the strip should be both annealed and rapidly cooled in order to have the absolute best in all of the properties that it brings to the table. It can be welded using many different techniques which includes but not limited to gas metal arc, resistance welding, and gas tungsten arc.
The HAYNES® 230® alloy can also be casted using standard techniques such as vacuum melt, air melt, or sand mold, although it is recommended that you use silicon levels at the high end of the specification range, mostly for the enhancement of its fluidity. Depending on what are you are using it for, you can cast HAYNES® 230® alloy strip in either as-cast or solution-heat-treated condition. With all of this flexibility, it is easy to see why this alloy is used by a number of professionals in a wide variety of industries.
If you are looking to build any machine that gets to extremely hot temperatures for long periods of time, consider HAYNES® 230® alloy for its construction. The chemical processing, aerospace, and power industries already take advantage of everything the strip has to offer, because they know that any failure can cost a considerable amount of time, money, and manpower to solve, all while inconveniencing their customers and employees, and at worst putting them in life or death situations. They require a strip that can be counted on to run perfectly every time, all the time, and over time. This is why time and time again they look to HAYNES® 230® alloy strip to do the job for them.
Elgiloy only provides premium quality components to our customers because we know that they depend on quality to do their jobs right. HAYNES® 230® alloy is one of the many alloys that we provide that meets and many times exceeds expectations for all of our customers. Contact us today for more information.
