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