Inconel® is a material that is specifically optimized for some of the toughest use conditions to be found in manufacturing while Duplex stainless steels is the most recent family of stainless steels. They are called duplex (or austenitic-ferritic) grades because their metallurgical structure consists of two phases, austenite (face-centered cubic lattice) and ferrite (body centered cubic lattice) in roughly equal proportions.

Inconel alloys
Alloys of inconel include:
- Inconel 600: Solid solution strengthened
- İnkonel 601
- Inconel 625: Acid resistant, good weldability. The LCF version is typically used in bellows.
- Inconel 690: Low cobalt content for nuclear applications, and low resistivity
- Inconel 713C: Precipitation hardenable nickel-chromium base cast alloy
- Inconel 718: Gamma double prime strengthened with good weldability
- Inconel 751: Increased aluminium content for improved rupture strength in the 1600 °F range
