CarTech Lapelloy "C" is an improved modification of Lapelloy which has a more homogeneous structure and more uniform fabrication behavior and mechanical properties. It has been used for highly stressed parts involving service temperatures up to 1200°F (649°C). CarTech Lapelloy "C" has greater ductility and impact strength at both room and elevated temperatures than conventional CarTech Lapelloy when heat treated to the same strength levels.

High mechanical properties can be developed by heat treatment. It has good resistance to scaling and oxidation for continuous service up to 1400°F (760°C). It has been used for compressor wheels, turbine shafts, compressor buckets, blades and bolts.
