THEIS-ITEŽTHEIS-ITE offers a combination of excellent formability and high strength. This allows for parts to be intricately shaped without expensive final hardening with its distortion and sorting problems. THEIS-ITE is supplied pre-tempered in thicknesses from 0.004" through 0.065" (0.10-1.65 mm) and widths from 0.25" through 12.5" (6.35-317.50 mm). Theis will custom make THEIS-ITE to suit your requirements. The table below shows some typical data of THEIS-ITE at various thicknesses.
