A seal ring for a seal assembly includes a body and a seal flange. The body is generally cylindrical and extends along a longitudinal axis between a load end and a seal end. The seal flange is disposed at the seal end of the cylindrical body. The seal flange circumscribes the body and projects radially from the body to a distal perimeter of the seal flange. The seal flange includes a sealing face which is annular and disposed adjacent the distal perimeter. The seal ring is made from an alloy that includes between 8 percent and 13 percent by weight of iron, between 2 percent and 3 percent by weight of silicon, between 13 percent and 14 percent by weight of chromium, and at least 65 percent by weight of nickel.

A method to produce cast iron articles with various graphite morphologies is disclosed that provides cast iron with tailored properties at different locations of the article. Flake graphite morphology is preferably created at locations requiring excellent thermal conductivity or lubricity. Spheroidal graphite morphology is preferably created at locations requiring excellent strength or mechanical fatigue life. These methods may be particularly valuable for the production of heavy duty diesel engine components.

Compactor tooth

Capactor teeth are normally utilized to provide crushing and/or grinding and compaction of refuse material and to compact soil on top of the refuse material. It is advantageous to provide a tooth that provides good traction of a capactor wheel and both good demolition and penetration of the material being crushed. In the subject arrangement, a tooth has an outer surface which has at least six edges with a plurality of side surfaces extending therefrom and angled with respect thereto at an obtuse angle. The tooth has a generally rectangular base with a longitudinal plane defined therein parallel to the length of the generally rectangular base. Apexes defined by the side surfaces are parallel with the longitudinal plane and angled with respect to the outer surface within the range of 115.degree.-135.degree.. The shape of the outer surface along with the plurality of side surfaces extending therefrom at an obtuse angle with respect to the outer surface provides a tooth that readily penetrates and compacts the refuse material and/or soil while providing good traction of the compactor wheel with respect to the materials being compacted.
