Stainless Steel SUS303 is also known as Stainless Steel Type 1.4305.  SUS303 is the most readily machineable of all the austensitic grades of stainless steel.  

The machineable nature of Grade 303 stainless steel is due to the presence of Sulphur in the steels composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of grade 303 stainless steel is lower than that for 304. The toughness is still excellent as with other austenitic grades.

Property data given in this document is typical for bar products covered by EN 10088-3:2005. ASTM, or other standards may cover products sold. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

Corrosion Resistance of Stainless Steel SS303 

Sulphur additions to the composition act as initiation sites for pitting corrosion. This decreases the corrosion resistance of grade 303 stainless steel to less than that for 304. However corrosion resistance remains good in mild environments.
In chloride containing environments over 60°C, grade 303 stainless steel is subject to pitting and crevice corrosion. Grade 303 stainless is not suitable for use in marine environments.

Heat Resistance of Stainless Steel SUS303 

Grade 303 stainless steel has good resistance to oxidation when intermittently exposed to temperature up to 760°C temperatures. It also has good oxidation resistance in continuous service to 870°C. This, however, is not recommended as 303 is sensitive to carbide precipitation with continuous use at 425-860°C.
