303 Product Guide Product   | 303 Stainless Steel Tolerance Guide product

The main value of 303 stainless steel is its ease of machining, grinding, and polishing due to the presence of sulfur 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. It is typically used in aircraft applications, machine parts, pump and valve parts, architectural applications, nuts, and bolts.

We carry 303 in square bar, cold drawn annealed square bar, rectangle bar, cold drawn annealed rectangle bar, HRAP rectangle bar, round bar, hex bar, sheet/plate, HRAP sheet/plate, and sample packs.
