ABSTRACT:
Apex seal for rotary piston engines made of an iron-based material containing in weight 2.5 to 4.0% of C, 0.5 to 2.8% of Si, less than 1.0% of Mn, 0.25 to 2.0% of Ni, 0.25 to 2.0% of Mo, 0.25 to 2.0% of Cu, 0.15 to 0.4% of B, 0.15 to 1.5% of Cr, 0.1 - 0.4% of V and the balance of substantially iron. The material is of a chilled structure which is produced when the material is casted without any specific cooling. The apex seal provides remarkably improved wear and impact resistant properties.
