The Monosteel^® piston provides the strength and cooling performance to meet the most arduous engine requirements in heavy-duty and industrial engine markets including the new generation of engine firing pressures required for Euro VI on-highway regulations and beyond.

The robust design - constructed of inertia welded, forged steel sections which create large cooling galleries - enable Monosteel pistons to withstand increasing mechanical loads.  Monosteel’s evolution includes recent developments for large bore industrial engines, and utilizing thin wall lightweight forgings and castings for light vehicle diesel engines.

Product highlights:

• A large, closed structural gallery with superior bowl rim and ring groove cooling, reducing groove distortion and improving oil control and gas sealing
• A profiled, bushingless pin bore
• A full-length skirt for stable piston dynamics, reducing risk of liner cavitation and improving ring sealing
• Process allows material flexibility with crown material options to reduce corrosion or oxidation, and/or skirt material options to improve manufacturability.
