Incoloy 800HT Tubing

Incoloy 800H and 800HT Tubing are primarily used for elevated temperature strength and diverse corrosive media for extensive operations like high temperature reactions including carburization and oxidation. Its scaling resistance is noticed in the aggressive cyclic oxidation analysis at the temperature ranges of 1800oF to 2000oF.
