Stainless Steel X10CrAl24

This grade of stainless steel finds applications in high-temperature environments due to its exceptional heat resistance. It maintains its mechanical strength and corrosion resistance at elevated temperatures, making it ideal for use in applications like industrial furnaces, exhaust systems, and heat exchangers. The addition of aluminum enhances its oxidation resistance, preventing the formation of scale at high temperatures.

Stainless Steel X10CrAl24 does not respond well to traditional quenching and tempering heat treatments like martensitic or austenitic stainless steels. Instead, it is typically annealed at temperatures around 950-1050°C (1742-1922°F) followed by air cooling to achieve desired properties.

In terms of machining, this grade can be machined using conventional methods but can be somewhat challenging due to its high chromium content, which can result in increased tool wear. Carbide tools and adequate cooling are often recommended to maintain tool life.

Availability of SS 446 can vary regionally, but it is generally accessible through specialized stainless steel suppliers and distributors. It is available in various forms, including sheets, plates, bars, and pipes, to cater to diverse industrial needs.

One of the standout features of X10CrAl24 is its exceptional heat resistance, allowing it to withstand temperatures up to 1100°C (2012°F) in continuous service, making it well-suited for applications involving sustained high temperatures. Its corrosion resistance is primarily limited to oxidation and scaling resistance, which means it may not be the best choice for applications requiring resistance to corrosive chemicals.
