Specify alloy steel blasting media using an agreed particle form, material identity and selected size.

Shot or grit

The title names both shot and grit, while the detail describes round particles. Confirm actual shape and any bearing-steel designation before approving the media rather than assuming round shot and angular grit are interchangeable.

Size selection

The title requests 0.4 and 1.2 mm, the actual grit entry reads 40, and the detail gives 0.2–2.5 mm. Establish the grading convention and particle distribution; do not translate the grit label into a diameter without evidence.

• Actual alloy records
• Shot or grit form
• Selected particle grading
• Hardness and density inspection
• Equipment and workpiece trial

Process approval

Agree blasting or peening acceptance for the actual media. SAE and ISO labels establish no certification, cleaning rate or peening performance on their own.
