る。The chemical composition of the present invention is as follows. simply%
When expressed by, the content is% by weight. C is necessary for improving the wear resistance due to the formation of high strength and net-like carbide, and at least 0.6% is necessary for its effect, and 1.0%
Beyond 10%, the precipitation of net-like carbides is too large, which adversely affects the transverse rupture strength, so the preferable range is 0.6 to 1.0%.

うになるので、２％までを好ましい範囲とする。[0008] Mn is also a deoxidizing agent and is an element inevitably present in general steel materials. It combines with sulfur to form MnS to increase machinability, but it increases hardenability and impairs toughness. Therefore, the preferable range is up to 2%.

In the case of cast steel, a small amount of Cr and V forms a solid solution in the matrix structure to increase the high-temperature strength, but when the content exceeds a certain level, a net-like carbide is formed to improve the slidability. Cr is effective in increasing rust resistance and oxidation resistance, and V is effective in refining the structure.
The range of 0.0 to 14.0% and V is 0.03 to 0.15%.

２％〜1.５％を好ましい範囲とする。Mo increases the strength, heat resistance and wear resistance at high temperatures. Further, it coexists with Cr to increase the corrosion resistance, and is particularly effective as an oil ring of a diesel internal combustion engine in which the corrosion resistance is a problem. 0.2% or more is necessary for Mo to exert these effects, but even if it contains 1.5% or more, its effect does not increase so much and the cost increases.
The preferable range is 2% to 1.5%.

The toughness is poor, and if it is too high, it is brittle and the workability is poor. In order to improve the slidability, at least the sliding surface of the piston ring material with respect to the cylinder wall is subjected to nitriding treatment.
