Heat resistance:

• Excellent oxidation and corrosion resistance at high temperatures up to approx. 1100 °C (2000 °F)
• Chromium, aluminium, and silicon form a protective oxide layer against degradation in hot environments
  
  

Corrosion resistance:

• Good resistance to many aggressive chemicals, especially oxidizing media
• Aluminium addition forms a stable protective alumina layer at high temperatures
  
  

Mechanical properties:

• Retains strength and toughness at high temperatures, with stable performance even near melting point
  
  

Resistance to thermal expansion:

• Low thermal expansion, suitable for applications requiring dimensional stability under heat loads
  
  

Weldability and machinability:

• Generally weldable with specific treatment required for optimal corrosion resistance and strength
• Machining requires specialized equipment due to hardness from high-temperature resistance
