Goetze K4 Piston Rings for 4-Stroke Large Bore Engines
KV4, a low-alloyed heat-treated nodular cast iron, is a preferred material for compression rings. For increased stresses a higher hardness is created by varying the martensite morphology. Bending strength > 1300 MPa with a high modulus of elasticity.
Spheroidal graphite cast iron
