Stainless Steel Sample Pack 303 Annealed Round offers an inexpensive way to make sure you get the correct material for your project. 303 is one of the easiest stainless steels to machine, grind and polish. Toughness and corrosion resistance is 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.
