The main value of stainless steel 303 is its ease of machining, grinding, and polishing due to the presence of Sulphur in the alloy. However, this slightly does lower the corrosion resistance and toughness of the metal. But despite this, it remains a tough, austenitic stainless steel alloy.
Stainless steel 303 is typically used in aircraft applications, machine parts, pump and valve parts, architectural applications, nuts, and bolts.
