Steel piston head

Steel piston heads are used for assembled pistons. A piston base and head are joined together to produce the necessary cooling duct. Steel piston heads enable complex contours (e.g. combustion cavities) to be forged into the upper side that do not require subsequent machining.

 

Technical specifications
