Goetze KV1 Piston Rings for 4-Stroke Large Bore Engines
KV1, a low-alloyed heat-treated nodular cast iron, is a preferred material for compression rings. It is characterized by a bending strength >1300 MPa and high modulus of elasticity due to its martensitic microstructure and spherulitic graphite structure.
