Nickel-based High Temperature Alloys
High temperature alloys are metallic materials made primarily of nickel, chromium and cobalt. These metals possess exceptional strength and heat resistance, which makes them suitable for applications where temperatures in the range of 800 to 1500 Fahrenheit are encountered. Without the use of these alloys, the temperature limits of a workpiece or component would be reached much more quickly.
High temperature alloys have superior properties. They exhibit good creep strength, excellent corrosion resistance and good oxidation resistance at temperatures above 800°F.They are also solid-solution strengthened, which allows them to retain their strength without the need for grain boundary precipitation.
In addition, these alloys can maintain a slightly higher temperature than other alloys. This is important when components are in an environment that tends to reach high temperatures. The higher temperatures allow components to remain safely in operation, regardless of the environment in which they are located.
These alloys are also remarkably light. They are stronger and more resistant to heat than heavier alloys, enabling manufacturers to produce products that can withstand high temperatures without adding extra weight.
High temperature alloys are used in a wide variety of applications. They are popular in jet engines, where temperatures can exceed 1000 Fahrenheit. They are also used in nuclear reactors and gas turbines. These alloys are also popular in automotive applications, such as exhaust systems and turbo chargers, where high temperature resistance is critical.
These alloys come in a wide variety of shapes and sizes, from pre-clad components to powder or wire form. Depending on the application and the environment the components are in, manufacturers can select the best alloy for the job. The selection process should take into account the specific microstructure, alloy composition and weld requirements.
High temperature alloys are also very cost-effective. The cost of production and processing is usually offset by the savings in energy use and the results in improved performance of the systems they are used in.
In summary, high temperature alloys are a valuable resource for manufacturing, especially in applications that require superior heat resistance. They are light, strong and cost-effective, providing a great benefit to industrial and commercial applications that must deal with extreme temperatures. They are available in many different forms and can be altered slightly to suit specific applications. This makes them a popular choice for those working with high temperature alloys.
