Goetze STD Piston Rings for 4-Stroke Large Bore Engines
The STD ring material is characterized by a fine-lamellar graphite structure in a pearlitic matrix and has good conformability due to a relatively low modulus of elasticity.
Non heat-treated grey cast iron
Main applications: compression rings, oil control rings
ISO 6621-3, subclass 12
Minimum bending strength: 350 MPa
Modulus of elasticity: 85 - 115 GPa
Ring diameter range: ≤ 700 mm
