Honest Horse S330 steel shot is presented with a2.5mm reference for peening. Actual model choices are S780,S660,S550,S460,S330 andS390 under Steel material.
Choose the S-model before sizing confirmation
Select one of the six model labels and request its particle distribution. The shared2.5mm parameter reference does not independently prove the grading of every model.
- Steel is the actual material.
- Six S-model labels are selectable.
- 2.5mm is the stated size reference.
- Round or spherical form is described.
- Shot peening is the named use.
Agree one mechanical condition
General53–64HRC and GP,GL,GH bands require a selected specification. Obtain actual composition and clarify the scope of the density and chromium references for the chosen model.
Request relevant standards and test evidence
Ask for applicable SAE J444 records and a representative process sample. High-tenacity wording and a brand label do not establish measured toughness or a peening result for the supplied shot.
