2.0 Grinding outer skin and structure
Do not use any abrasives (grinding wheels, paper, etc.) which contain iron (risk of corrosion).
Always replace abrasives which have already been used to treat steel (risk of corrosion).
Use stainless steel wire brushes only (risk of corrosion).
Reduce speed of grinding machines. Excessive speeds cause a smearing effect.
Do not use coarse abrasive grains (only ≥ 80).
Do not grind notches into the material (risk of cracking).
Do not grind the material thin.
