S330 alloy steel shot is described with a1.0mm reference for medium and small casting-part cleaning. The actual configuration pairs Alloy Steel,grit18 and a0.2–3.0mm range rather than a dedicated1.0mm selection.
Confirm the S330 physical distribution
Request the supplied grading that meets the1.0mm requirement. The numeric grit and range label should not independently be treated as proof of that diameter.
- Alloy Steel is the actual material.
- Grit18 is the selectable label.
- 1.0mm is the parameter reference.
- Spherical form is described.
- Rust removal and polishing are named uses.
Choose the hardness for the casting surface
General42–53HRC and additional hardness bands need one agreed condition. Provide the casting material and finish requirement before selecting the abrasive.
Request process and durability evidence
The stated density is a technical reference to verify with the medium. Wear resistance,breakage resistance and long life require applicable tests;request composition and any required SAE J444 records for the S330 offer.
