Finishing stainless steel for food-grade applications

  • Judge A Book by Its Cover, and The Story InsideChoosing Abrasives and ToolsNeed A Little Direction?Polish The Approach and The End Is in SightIn the majority of applications, a finish at the high end of No. 4 is considered food grade (see Stainless Steel Finishessidebar). This finish is achieved using a high-grit abrasive in the range of 150-220 and is identified by short, parallel lines that run the length of the material. The success of the finish can ultimately be determined by a surface roughness average (Ra),measured by height in millionths of an inch (µin.), or microinches. A profilometer determines Ra values by moving a diamond stylus across thSanitary Welding - Certified Sheet Metal & Certified Sanitary Welding.
