Stainless Steel Materials used for Machining

• SUS 303:

   

  • Nuts and Bolts, Bushings, Shafts, Aircraft Fittings, Gears.

     

  • Electrical Switchgear Components.

     

  • In general any component that is heavily machined and where the corrosion resistance and fabrication properties of 303 are viable.

     

• SUS 304:

   

  • Food processing equipment, particularly in beer brewing, milk processing & wine making.

     

  • Kitchen benches, sinks, troughs, equipment and appliances.

     

  • Architectural panelling, railings & trim.

     

  • Chemical containers, including for transport.

     

  • Heat Exchangers.

     

  • Woven or welded screens for mining, quarrying & water filtration.

     

  • Threaded fasteners, Springs.

     

• SUS 316:

   

  • Food preparation equipment particularly in chloride environments.

     

  • Laboratory benches & equipment, Threaded fasteners, Springs.

     

  • Coastal architectural panelling, railings & trim.

     

  • Boat fittings, Chemical containers, including for transport.

     

  • Heat Exchangers, Woven or welded screens for mining, quarrying & water filtration.

     

  • 316Higher resistance to pitting and crevice corrosion is required, in chloride environments. A lower machining ability can be accepted.

     

• SUS 416:

   

  • Valve Parts, Pump Shafts, Automatic Screw Machined Parts.

     

  • Motor Shafts, Washing Machine Components.

     

  • Bolts and Nuts, Studs, Gears.

     

  • Even higher machining ability than 303 is needed, and a lower corrosion resistance can be tolerated. Or hardening by thermal treatment is required, while maintaining a high machining ability.
