RESDA cast steel shot has one actual7–120/Steel/S460/S550/S660/S780 triple. The slash-separated specification is one combined label, not four individually defined actual variants.
Select the actual grading
Choose one intended size designation and request actual particle distribution. The body model family ends at S660, so S780 in the actual label needs selected-batch confirmation.
- Round shape.
- Black color.
- 40–50HRC hardness reference.
- 4.2g/cm³ bulk-density field.
- SAE J444 standard reference.
Check durability evidence
The2800Times field has no stated test method or acceptance endpoint. Request its actual basis instead of treating it as guaranteed service cycles.
Define blasting acceptance
Agree substrate, equipment and finish criteria with actual grading and hardness inspection. High-density and low-consumption title wording supplies no universal cleaning result or operating-cost guarantee.
