A seal ring comprising a boron containing cast iron composition is disclosed. The cast iron composition particularly comprises each of boron, chromium and silicon in the following amounts: boron up to 1 wt. %; chromium up to 4 wt. %; and silicon up to 2 wt. %. The seal ring may be produced by melting a cast iron composition further comprising the foregoing alloying elements; pouring the melted alloy into a mold; cooling the melted alloy to form a cast iron seal ring; and separating the cast iron seal ring from the mold. The seal ring is typically used in the undercarriage of earth-working machines, such as in the drive train or power train of such machines.
