S330 or S390 steel shot enquiries should confirm the supplied particle form before a blasting trial. For S330, clarify a hollow-particle requirement before comparing replacement media.

• Steel is the actual material choice.
• S280, S330, S390 and S460 are grit options.
• Round is the stated shape.
• Shot peening is the described use.
• The stated hardness is 40-50HRC.

Clarify the particle structure

Ask what hollow-particle form means for the proposed S330 supply. Confirm actual particle integrity and acceptance criteria instead of assuming a solid shot structure.

Select the required S designation

The grit menu contains four S-series choices. Confirm the grading and applicable technical specification for the selected S330 or S390 medium.

Assess the peening process

Provide the workpiece and process requirements for the round steel shot. Obtain relevant composition and particle-quality evidence before treating the medium as an approved replacement for a controlled peening operation.
