• Alloy 20 Details

  
  
  

  Alloy 20 is a high alloy corrosion-resistant material mainly composed of chromium, nickel, molybdenum, copper, etc. It has excellent corrosion resistance and stress corrosion cracking resistance, and is widely used in fields such as chemical, petroleum, pharmaceutical, and food. Below is a comprehensive introduction to Alloy 20.

  
  

  Alloy 20 physical property:

  Alloy 20 has a density of 8.1 g/cm3, a melting point of 1350-1370 ℃, and a linear expansion coefficient of 12.4 μ M/m-K, with a thermal conductivity of 14.6 W/m-K. It has good processing and welding performance at the same time, and can be used to manufacture various shapes of parts.

  
  

  Alloy 20 corrosion resistance:

  Alloy 20 has excellent corrosion resistance and excellent corrosion resistance in many corrosive media. It can work stably in high-temperature and acidic environments for a long time, and has good corrosion resistance to most acid, alkali, salt and other media. In addition, it also has good oxidation and reduction performance and excellent anti-corrosion performance.

  
  

  Alloy 20 mechanical properties:

  The mechanical properties of Alloy 20 are also very good, with a tensile strength of 690 MPa and a yield strength of 315 MPa. It has good plasticity and crack propagation resistance, so it can maintain stable performance even in high stress environments. In addition, it also has good impact strength and fatigue strength.
