Heat resistance:

• Temperature resistant up to approx. 1150 °C
• High oxidation resistance due to chromium, silicon, and rare earth elements forming a dense oxide layer
• Good resistance against creep and thermal fatigue at extreme temperatures
  
  

Corrosion resistance:

• Excellent in oxidizing and mildly reducing atmospheres at high temperatures
• Not suitable for sulfurous or strongly reducing atmospheres
• Limited resistance to aqueous corrosion (e.g., pitting in chloride environments)
  
  

Mechanical properties:

• Tensile strength: 600–750 MPa (at room temperature)
• Yield strength: ≥ 310 MPa (at room temperature)
• Good mechanical stability at elevated temperatures due to nitrogen and carbon additions
• Good creep resistance for long-term applications
  
  

Weldability:

• Very good weldability with common processes (TIG, MIG, MAG, etc.)
• No post-weld heat treatment required
• Filler materials such as 1.4835 or AISI 309 recommended
  
  

Formability:

• Good hot formability between 900 and 1200 °C
• Cold forming is limited due to high strength and hardness
