Title:
ピストンリングおよびシリンダライナの製造のための高珪素成分を含む鋼材
Document Type and Number:
Japanese Patent JP5669392
Kind Code:
B2
Abstract:
The invention relates to a steel material having a high silicon content, and to a method for the production thereof, the steel material being particularly suitable for piston rings and cylinder sleeves. In addition to iron and production-related impurities, the steel material contains 0.5 to 1.2 wt. % carbon, 3.0 to 15.0 wt. % silicon and 0.5 to 4.5 wt. % nickel. Also, the steel material can contain small amounts of the following elements Mo, Mn, Al, Co Nb, Ti, V, Sn, Mg, B, Te Ta La, Bi, Zr, Sb, Ca, Sr, Cer, rare earth metals and nucleating agents such as NiMg, MiSiMg, FeMg and FeSIMg. due to the high Si content, a degree of saturation higher than 1.0 is attained, with the melting temperature of the steel material corresponding to normal cast iron. The steel material can be produced according to a conventional cast-iron technique and has a high resistance to wear and tear and a high structural strength (minimal distortion).
