Cold Rolling Ultra-High Strength Alloy Steel Into a Gear

Cold Rolling Gears

Carpenter Technology demonstrate the cold rolling of their PremoMet alloy, a ultra-high strength alloy steel, into a gear. More information is provided from their video description below:

Gear manufacturers are beginning to see the benefits from cold formed automotive gears compared to traditional hobbed and forged gears. This video shows Carpenter’s ultra-high strength alloy steel in bar form, PremoMet alloy, being cold rolled into a gear by a gear manufacturer. 

The advantages of the cold rolling manufacturing method include reduced cycle times, improved yield and excellent surface condition with minimal tooth distortion. Upon testing, the gear withstood higher load capacity with no damage or wear.
