Abstract
A compressor slider has a carbon content of 2.0 wt % to 2.7 wt %, a silicon content of 1.0 wt % to 3.0 wt %, a balance of iron that includes unavoidable impurities, graphite that is smaller than the flake graphite of flake graphite cast iron, and a hardness that is greater than HRB 90 but less than HRB 100 in at least a portion of the slider.
Claims20
A compressor slider comprising:
- a carbon content of 2.0 wt % to 2.7 wt %;
- a silicon content of 1.0 wt % to 3.0 wt %;
- a balance of iron having unavoidable impurities;
- a metal structure being primarily composed of a pearlite structure, a ferrite structure, and granular graphite;
- and
- a hardness being greater than HRB 90 and less than HRB 100 in at least a portion of the slider.
