Inconel® Alloys Table

Inconel Alloy	Characteristics
188	Often used for commercial gas turbine and aerospace applications.
600	Solid solution strengthened
625	Acid resistant, good weldability. The LCF version is typically used in bellows.
690	Low cobalt content for nuclear applications, and low resistivity
713C	Precipitaion hardenable nickel-chromium base cast alloy
718	Gamma double prime strengthened with good weldability
751	Increased aluminium content for improved rupture strength in the 1600 °F range
792	Increased aluminium content for improved high temperature corrosion properties, used especially in gas turbines
939	Gamma prime strengthened to increase weldability

In age hardening or precipitation strengthening varieties, alloying additions of aluminum and titanium combine with nickel to form the intermetallic compound Ni3(Ti,Al) or gamma prime (γ'). Gamma prime forms small cubic crystals that inhibit slip and creep effectively at elevated temperatures.
