The retention ring clips are made of AISI 4140 carbon steel. The blank is made by hot forging. After hot forging, the clips construction is more steady and stronger. The CT and BT style ATC-0028 retention ring clips are also CNC machined to the precise size. The flatness is +/-0.1mm. Heat treatment is requested to reach higher hardness. The hardness is HRC 52. They are durable and good working. Black oxide is requested to avoid rust.
