• Alloy 783 Details

  
  
  

  ALLOY 783 alloy is a high-temperature alloy with oxidation resistance and low thermal expansion coefficient, specifically developed for steam turbine applications. After adding niobium and aluminum, the strength of 783 alloy was improved through precipitation hardening heat treatment. In addition, the content of aluminum also makes it have good antioxidant properties at high temperatures.
