Al-Fe Heat Treating: Defiance, OH – Plant 2

2092 East Second Street      •      Defiance, OH 43512      •      (419) 782.7200

Defiance Plant 2 opened in 2007 to provide continuous stress relieving of the Duramax iron engine blocks for General Motors.

Continuous Ferrous Stress Relieving

Stresses imparted in the engine block castings during the cooling cycle are addressed with this stabilizing heat treat process. Following stress relieving Al-Fe utilizes a fully automated robotic shot blasting system to clean the blocks prior to machining. Soon, this facility will be retooled for a high-volume aluminum cylinder head program.
