What is Nitronic 60?
Nitronic 60 (UNS S21800) is a high-silicon, nitrogen-strengthened austenitic stainless steel that achieves excellent intermetallic wear resistance without heat treatment. It is primarily used to provide superior wear and abrasion resistance while still maintaining good corrosion resistance. It is available in various practical product forms, including plates, coils, tubes, bars, and wires.
What is Inconel 718?
Inconel 718 (UNS N07718) is a precipitation-hardened nickel-based superalloy designed for extremely high strength at elevated temperatures. It exhibits very high tensile and creep strength at temperatures up to approximately 650°C (1200°F), making it particularly suitable for aerospace, energy, and high-pressure environments.

| Heat Treatment Required | No | Yes (solution + aging) |
| Fabrication Cost | Lower | High |
Which is more expensive, Inconel 718 or Nitronic 60?
Inconel 718 is generally significantly more expensive than Nitronic 60 because Inconel 718 is a high-nickel superalloy with much higher precious metal content (Nickel, Chromium) and complex processing, targeting extreme high-temp/corrosion uses, while Nitronic 60 is a specialized stainless steel with silicon/manganese for wear/galling, making it pricier than regular stainless but less than Inconel.
