A refined version of IN 738C with lower carbon content, IN 738 LC offers improved weldability and consistent mechanical properties for both equiaxed and directionally solidified turbine blade casting. Its balanced chromium and refractory element content delivers strong creep rupture life alongside good resistance to type I and type II hot corrosion. Newly qualified to AMS 5410 and supported by MSRR 7173, IN 738 LC is a primary blade alloy for industrial and aero-derivative gas turbines.
