Stainless Centerless Ground Round Bar 303 is one of the easiest stainless steel alloys to machine, grind, and polish. Therefore, toughness and corrosion resistance are slightly lower than most other stainless steels as a result. 303 is typically used in aircraft applications, machine parts, pump parts and valve parts, architectural applications, nuts, and bolts.
