Automotive Gear Manufacturing
In a very giant gear contour heating shall be more economical since coils become very expensive as they improve in dimension. The success of many flame hardening operations for small production runs relies on the talent of the operators. Case hardening is used to provide automotive gears a tough, wear-resistant case, or floor layer, on prime of a ductile, shock-resistant interior, or core. The thought behind case hardening is to maintain the core of the gear tooth at a stage round HRC to avoid tooth breakage whereas hardening the outer surface to increase pitting resistance.
