Choose an actual steel shot designation and batch distribution before requesting blasting media.

Code selection

The title names S280 and S390 while the actual specification is S280. Confirm actual grading convention and any requested S390 supply instead of treating both codes as verified variants or converting them into unsupported particle diameters.

Batch condition

The detail identifies round black steel shot with hardness and bulk density references. Agree actual particle distribution, condition and inspection method matched to the proposed machine and carbon metal workpiece.

• Actual S280 or requested S390
• Grading and batch distribution
• Round particle inspection
• Hardness and density records
• Source and workpiece trial

Supply evidence

RESDA, manufacturer and efficiency wording provides no verified source or process result. Request actual records; no manufacturer identity, certified grading, reuse lifetime or guaranteed cleaning outcome is established.
