Gray cast iron (SCh250, SCh300) is widely used for machine frames, engine blocks and body parts due to its good machinability and ability to dampen vibrations.
Cast iron mooring bollards are essential mooring devices widely installed on quays, piers and jetties to reliably transfer mooring forces from moored vessels to the pier structure.
