Daros GP50 Piston Rings for 2-Stroke Large Bore Engines
The GP50 (CGI) high strength cast iron ring material is characterized by a vermicular graphite structure with pearlitic matrix and special carbides for LBE applications.
Technological properties: high strength above 145 mm nominal diameter
ISO 6621-3, subclass 50
Minimum bending strength: 900 MPa
Modulus of elasticity: minimum 140 GPa
Ring diameter range: ≤ 1000 mm
In order to satisfy the high requirements for piston rings, the basic material used in Federal-Mogul Powertrain piston rings comprises high-quality lamellar or spherolithic cast materials. The basic material is selected from a wide range according to application and fuel quality.
