Advantages and Disadvantages of Inconel Alloy 702


  • Excellent Corrosion Resistance: It is also characterized by high abrasion and corrosion resistance when subjected to both fresh and salt water, acids, alkalis, etc.

  • High Temperature Stability: It has good high temperature properties: it retains its strength and other mechanical properties at high temperature, hence is good for high temperature uses.

  • Good Weldability: Shows good weldability, and can be easily fabricated to the desired shape and assembled mostly through welding processes.

  • High Strength: High-strength, good creep strength satisfied many high stress part used in gas turbines or steam generators.


  • Limited Availability: It could also have issues of rarity hence causing complications in the supply chain.

  • High Cost: Largely more costly than other material do to its production, this may affect the costs of specific projects.

  • Machining Difficulty: Due to its hardness and its resistance it has these features it requires special cutting to be done hence time and costs of machining are relatively high.

  • Sensitivity to Hot Cracking: Is prone to hot cracking during welding and should be welded under controlled conditions depending on the chosen parameters for welding our material.
