Welcome to INEX

Introduced in 1988, INEX specializes in Composite Radiant Tubes (CRTs) used for indirect heat-treating processes. Formed using our patented, melt-infiltration process, our tubes consist of Silicon Carbide (SiC) particles reinforcing a continuous Silicon (Si) metal-matrix. These composite materials completely eliminate common problems associated with metal alloy radiant tubes that suffer from Creep (deformation, distortion & rupture), Carburization (embrittlement & corrosion), Thermal Shock, Melt-Through, Weld Failure and Oxidation to 2450°F (1340°C).
