S660/S2.0mm high carbon cast steel shot provides a defined model for blasting and rust-removal enquiries. Confirm the supplied grading and process requirements before replacing an existing abrasive.
- Cast Steel is the material option.
- S660/S2.0mm is the specification.
- 10-12 is the grit label.
- Round is the particle shape.
- The stated hardness is 42-53HRC.
Match the S660 particle specification
Provide the required S660 size distribution with the enquiry. Ask how the grit label 10-12 relates to the S2.0mm specification rather than assuming a separate diameter conversion.
Review the high-carbon composition
The technical description gives a carbon range and other elemental limits. Request the relevant material analysis for the supplied cast shot when chemistry forms part of acceptance.
Assess the cleaning process
Give the supplier the machine and workpiece conditions for the rust-removal trial. Standards and a durability figure require relevant evidence; they do not establish universal compliance or guaranteed reuse cycles.
