Inconel® alloy 783
A coefficient of thermal expansion approximately 20% lower than that of INCONEL alloy 718.
Excellent resistance to oxidation, demonstrated in cyclic tests, at temperatures up to and beyond 1300°F (704°C).
Resistance to SAGBO (stress accelerated grain boundary oxidation) comparable to that of INCONEL alloy 718, and significantly better than that of INCOLOY alloy 909.
A density of 0.282 lb/in 3 (7.81 g/cm 3 ), 5% less than INCONEL alloy 718 or INCOLOY® alloy 909, contributing to an important potential improvement in strength-to-weight ratios.
Manufacturing/processing characteristics comparable to those of INCONEL alloy 718, and less limiting than those of INCOLOY alloy 909.
Special Metals' INCONEL alloy 783 is available as forging billet (AMS 5940), rod and bar for machining, extruded section, and wire rod. Sheet product is currently under development.
