Choosing the Right Alloys for High Temperature Service
For any business involved in working with alloys in extremely hot environments, choosing the right alloys for high temperature service is far from straightforward. After all, there is no such thing as uniformity when it comes to working in extreme temperature.
Alloys for High Temperature – Resisting The Heat
Every alloy has properties that will make it react differently than every other alloy when subjected to prolonged periods of high temperature so it is vital that you check the technical data describing the properties of the metal in question before deciding if it is the alloy for you.
Quite often the temperature is the first, and in some cases only data point that most people look at when basing their choice of alloy…this is absolutely the wrong thing to do. It cannot be overstated that an alloy cannot, nor should not be chosen on the basis of temperature alone, there are a number of other things to take into consideration. These include:
- The mechanical properties of the alloy at temperature
- The alloys resistance to oxidation
- The alloys resistance to hot corrosion
- The metallurgical stability of the material
Committed to Quality
At NeoNickel we specialise in providing the very best specialty metals to companies the world over who demand high quality alloys that remain stable, durable and reliable in the face of extreme temperatures. Having supplied businesses of all sizes in the Aerospace, Nuclear, Pharmaceutical, Motorsport and Energy industries for many years we have the experience and expertise to give anyone looking at choosing the right alloy for high temperature service exactly what they need.
Vast Inventory of Heat Resistant Alloys
Our vast inventory includes RA330, which has become the standard material in the steel heat treating industry and combines good oxidation resistance with a high melting point, thus tolerating extreme temperatures of up to 1200 degrees C, (2200 degrees F). It has proven to be extremely popular as it is available in the widest range of product forms, (sheet, plate up through 4”, threaded bar, nuts, pipe and expanded metal), making it a versatile alloy with many applications in the heat treating and petrochemical industries.
602A is an austenitic heat resistant alloy that displays superior strength in the face of temperatures of up to 1200 degrees C, (2200 degrees F). In fact it is the single strongest and most oxidation resistant wrought alloy currently available for service above 1040 degrees C, (1900 degrees F). The outstanding strength displayed by this alloy has seen its popularity flourish, where it is used in applications including vacuum furnace fixturing, CVD retorts; rotary calciners and gas fired radiant tubes.
These are just a few examples of our range of heat resistant alloys that have made NeoNickel one of Europe’s most trusted suppliers of high quality specialty metals; metals that thrive and flourish under the most intense of environments. However, this really is the tip of the iceberg. There are many more alloys in our inventory; all with properties suited to different applications at wildly varying temperatures.
