Abstract

A cylinder liner with high strength and wear resistance and a manufacturing method thereof. The composition (% by mass) of the cylinder liner is as follows: C: 3.0-3.3%, Si: 2.0-2.3%, P: 0.3-0.6%, S: <0.1%, Mn: 0.3-0.6%, Mo: 0.1-0.3%, Nb: 0.08-0.15%, and the balance Fe. The structure of the cylinder liner is phosphorus-containing acicular ferrite and carbon-rich austenite, wherein the phosphide eutectic is no less than 3%. The cylinder liner has a hardness of HRC38-43, Rm>400 MPa, high strength and good wear resistance, solves the problem of pearlite cylinder liner with low wear resistance and cast bainite with bad corrosion resistance.
