Main Features of Steel Beads

- Ultramicro, spherically-shaped particles made by the Nitrogen Gas Atomizing method.
- Great effect in surface peening for precision metal parts.
- Applicable also for aluminum parts as flame spray coating.

Shot peening treatment with Steel Beads will increase strength of metal parts, reducing needs of parts enlargement for strengthening purposes.

Measurement Results about Steel Beads

Measured Data of Residual Stress

Measured Data of Residual Stress

By shot peening process, a large residual stress is given to 10µm depth from surface.

Measured Chart of Surface Roughness

Measured Chart of Surface Roughness

Surface roughness of approximately Ra 0.2 remains even after shot peening treatment.
