How to Create #4 Stainless Steel Finish
No. 4 finish is a popular polishing choice for several industries and products. It is characterized by short, parallel polishing lines and is the easiest of the stainless finishes to maintain. The final finish will depend on the material’s application and can range between 120 – 320 grit.
There are 4 basic steps for creating or blending a #4 stainless steel finish:
- Leveling the Weld – we suggest using either a Resin Fiber Sanding Disc or a Flap Disc
- Setting the Grain – we suggest using either a Belt or a Flap Wheel
- Final Finishing – we suggest using a Surface Condition Belt
- Final Blending/ Touch Up – we suggest using a Hand Pad
