What is heat treatment?

Heat treatment is a technique for metals and alloys to "toughen". The metal is transformed from brittle martensite into bainite or ferrite. Precise control of time and temperature during the tempering (heat treatment) process are critical to achieve a metal with well balanced mechanical properties.

  • In order to use this pinion gear on a clodbuster, you will have to get an adjustable motor mount.
