Material properties

UNS J92605, designated under ASTM A297 HC, is a cast ferritic stainless steel known for its excellent resistance to oxidation and high-temperature corrosion. It is ideal for use under high thermal stress conditions, maintaining substantial mechanical properties at elevated temperatures. This alloy, commonly referred to as 28Cr, is beneficial in environments that demand high durability and resistance to heat and chemical degradation.


Advantage

  1. High resistance to scaling and corrosion.
  2. Maintains integrity under high temperatures.
  3. Excellent for casting due to fluidity.
  4. Durable in oxidative environments.
  5. Suitable for high-temperature applications.

 

Application

UNS J92605 is primarily used in industries like petrochemical, energy, and environmental technologies, especially in applications involving furnaces, heat exchangers, and other high-temperature processing equipment. The alloy's resistance to sulfur-rich and oxidizing atmospheres makes it a valuable component in settings that require both heat resistance and longevity.
