Abstract: A cylinder liner is formed from a cylinder liner blank which includes a cylinder liner body having cylindrical sidewalls which define an internal diameter, an external diameter and a cylindrical lower extent. The cylinder liner blank is formed from a class of carbon alloy steels. A manufacturing method is shown for providing the cylinder liner blank with a flanged region at an upper extent of the cylindrical body by utilizing a cold forging process.
