Material properties

UNS J92603, also known under ASTM A297 as grade HF, is a high chromium nickel heat-resistant stainless steel known for its excellent oxidation resistance and high strength at elevated temperatures. This austenitic stainless steel is primarily used in casting applications where high temperature and corrosion resistance are required. It is characterized by its ability to withstand corrosive environments while maintaining a stable structure, making it ideal for high-temperature industrial applications.


Advantage

  1. High resistance to oxidation and corrosion.
  2. Maintains strength at high temperatures.
  3. Good ductility in heated conditions.
  4. Resistant to scaling up to approximately 1150°C.
  5. Suitable for complex shaping and forming due to its castability.

 

Application

UNS J92603 is widely used in industries requiring resistance to high temperatures and corrosive environments, such as petrochemical processing, heat treating equipment, and power generation facilities. Common applications include furnace parts, petrochemical equipment, heat exchangers, and other components exposed to corrosive gases at high temperatures.
