Welcome to INEX

INEX specializes in Composite Radiant Tubes (CRTs) used for indirect heat-treating processes. Our tubes consist of Silicon Carbide (SiC) particles reinforcing a continuous Silicon (Si) metal-matrix formed using our patented melt-infiltration process. Introduced in 1988, 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).
