Fabrication

The challenge of attaining dimensional accuracy in a component with such a thin, large-diameter shape was overcome with process optimization and the choice of steam treatment. Wear resistance and durability were also key for a successful part.

The parts have a density of 6.7 g/cm³, a tensile strength of 284 MPa, a compressive yield strength of 490 MPa, an elongation of 0.3%, and a 97 HRB hardness.

Results

This redesign of a previous PM part achieved a 17% weight reduction with increased dimensional accuracy.
