The reduced carbon content of IN 713 LC compared to IN 713C improves grain boundary weldability while maintaining strong precipitation-hardened creep and tensile performance for cast turbine blades and vanes. Qualified to AMS 5377 and supported by OEM specifications including B50T1239, MSRR 7048, and EMS 55079, it is used in both aerospace and industrial gas turbine applications where reliable cast strength and post-service repair capability are required.
