ABSTRACT:
A piston ring having an improved wear resistance and antiseizure properties and good workability is disclosed. The piston ring is made of a martensite stainless steel comprising from 0.4 to 0.7 wt % C, 0.3 to 1.0 wt % Si, 0.5 to 1.0 wt % Mn, and 2.0 to 9.0 wt % Cr, the balance being iron and impurities. Additionally, a surface-treated layer having a quench and temper hardness (H.sub.R C) of 40 to 50 is formed on at least that part of the piston ring which slides against the wall of a cylinder in which reciprocates a piston on which the piston ring is mounted. Preferably, the surface-treated layer is formed by hard Cr plating.
