		We manufacture gear hubs and gear sleeves with spur profiles. These together form gear couplings for mechanical power transmission between drive and driven equipment. One of our customers requires the teeth of components to be case hardened and depth of case hardening should be 0.8 to 1.2 mm. Please guide us which material we should use for the gears and the process of hardening. The profile of hardening should be parallel to that of gear tooth profile. Teeth width is small, in the range of 4 to 5 mm.
