Agree actual rust removal and surface inspection requirements before selecting GH40 steel grit.

Particle specification

GH40 is the actual menu specification with a separate 7–120 grit field. Confirm grading convention and batch particle distribution rather than inferring an exact size or surface profile from the model code alone.

Workpiece trial

The record identifies irregular steel particles with hardness and density references. Inspect actual batch condition and define machine settings, workpiece state and acceptance criteria for the intended shipbuilding or automotive operation.

• Actual GH40 grading
• Irregular particle sample
• Hardness and density scope
• Workpiece rust condition
• Surface preparation trial

Industry evidence

Derusting, durability and industry labels provide no qualified process result. Request actual material and trial records; no ship or automotive approval, guaranteed cleanliness, coating adhesion, reuse lifetime or productivity is established.
