303 Stainless Steel

If you are looking for a grade of austenitic stainless steel that would be optimal for machining, 303 Stainless Steel has the compositional properties that make it the ideal candidate. This steel is especially optimum for extensive machining practices because of the increased level of sulfur present in its composition. Note though the sulfur does lower the corrosion resistance, as well as weldability and formability of 303 compared to say the toughness found in 304 Stainless Steel.

Carbon .10%, Manganese 2.00%, Phosphorus .45%, Sulfur .15%, Silicon 1.00%, Chromium 17-19.00%, Nickel 8.00-10.00%, Iron Balanced.
