Corrosion and Oxidisation Resistance of 303.

303 stainless Steel shows good corrosion and oxidisation resistance in mildly corrosive atmospheric environments. Its sulphide inclusions act as pit initiation sites meaning it provides a lot less resistance than 304. Grade 303 should not be exposed to marine or other similar environments, to prevent rapid pitting corrosion. EN 1.4305 303 stainless steel provides good oxidisation resistance in intermittent service to 760°C (1400°F) and continuous service to 870°C (1,598°F) The use of 303 stainless steel is not recommended in the range of 425-860°C (797-1580°F) due to carbide precipitation. 303 is susceptible to sensitisation.

Stainless Steel

Type 303 stainless steel is an alloy which is the most readily machinable austenitic stainless steel available today.

Characteristics

Superior machinability is due to the presence of sulphur in the material composition, although improved machinability is at a cost – the sulphur content results in a decrease in corrosion resistance and also a slight lowering in toughness. But as with most austenitic grades, the toughness is still excellent. Weldability of the alloy is poor. Type 303 finds use in a variety of engineering applications.

Suitability

The material is an austenitic steel grade with better machinability but reduced formability. The material is not recommended for applications where welding is required. Type 303 has lower corrosion resistance when compared with 1.4301.

Typical Applications

Commercial applications for this engineering material include:

  • Aircraft fittings
  • Gears
  • Nuts and bolts
  • Electrical switchgear components
  • Bushings
  • Shafts
