Introduction
Super alloys or high performance alloys have the capacity to function at very high temperatures and mechanical stress, and also where high surface stability is required. They have high creep and oxidation resistance, and can be found in a variety of shapes. They can be strengthened by solid-solution hardening, work hardening, and precipitation hardening.
FeCralloy has good versatility. The following datasheet provides more details about FeCralloy.
