  Remainder

Round steel shot is described for shot peening with a hardness of 40-50HRC. The actual configuration uses grit 20 and steel shot as the material choice.

Confirm the delivered S-series size

S70-S780 is the model range rather than a single particle distribution. Request the specific delivered designation and confirm how grit 20 relates to that requirement before approving a peening-media batch.

• Shot peening is the stated use.
• Round is the particle-shape description.
• 40-50HRC is the stated hardness range.

Resolve composition and particle form

A stainless requirement needs a confirmed alloy specification rather than the title alone. Also verify the required solid or hollow particle condition and the supplied metallurgy before treating the media as equivalent to an established peening specification.

Validate the precision process

Obtain the applicable batch hardness, size and composition evidence. The peening result depends on the controlled treatment, so a precision label does not establish fatigue improvement or universal suitability for a workpiece.
