OVERVIEW SPECIFICATIONS AND TECHNICAL INFORMATION

See Stainless Steel Tolerances

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.
