Stainless Steel 303

Stainless 303 is the most easily machined of all the austenitic grades. 

Austenitic steels are highly ductile and have a tendency to work harden and form build up edges on the cutting tools. 

The addition of sulphur to the alloy improves its machinability but reduces its corrosion resistance. Nevertheless, it maintains good corrosion resistance in mildly corrosive environments and at temperatures up to about 60oC.
