Thermospan alloy

Thermospan alloy is a trademark of Carpenter Technology Corp. It is a precipitation-hardenable superalloy having an excellent combination of tensile properties and stress-rupture strength in the recrystallized condition with the use of common solution and age-hardening treatments. The alloy also exhibits a low coefficient of expansion over a broad temperature range. 

As a result of the chromium addition, significant improvements in environmental resistance over that of the CTX alloys is realized. 

The alloy should be considered for applications in which other current low-expansion superalloys are presently used, such as compressor and exhaust casings, seals, and other gas turbine engine components.
