S390 alloy steel shot is presented for rust removal, polishing and grinding inquiries. Spherical particles and a 1.2mm grain reference are described.

Resolve the delivered S390 size

The actual combination uses grit 25, Alloy Steel and a 0.2-3.0mm specification. Request the exact distribution and designation instead of assuming the numeric grit or broad range defines 1.2mm media.

• Alloy Steel is the actual material choice.
• Spherical is the particle description.
• Rust removal and polishing are stated uses.

Select one hardness condition

The general hardness and additional class ranges need an applicable batch specification. Obtain the test basis for the selected media rather than combining those values.

Check standards and process acceptance

Request SAE J444 evidence if required and assess the abrasive on representative workpieces. A trusted-manufacturer or high-quality phrase does not establish certified compliance, a guaranteed finish or a peening result.
