303 Stainless Steel Sheets Plates ASTM JIS GB Stainless Sheets 0.3
- 20.0mm UNS S30300
Grade 303 represents the optimum in machinability among the
austenitic stainless steels. It is primarily used when production
involves extensive machining in automatic screw machines.
Machinability Rating (compared to B1212) is approximately 78%.
303 is also available as a "Ugima" Improved Machinability grade,
with machinability even higher than that of the standard 303.
The sulphur addition which is responsible for the improved
machining and galling characteristics of Grade 303 lowers its
corrosion resistance to below that of Grade 304. As for other
austenitic grades the structure gives 303 excellent toughness,
although the sulphur in 303 reduces its toughness slightly.
Grade 303Se (UNS S30323) has a selenium rather than sulphur
addition, improving the hot and cold forming characteristics over
those of 303 and providing a smoother machined surface finish. The
machinability rate is also slightly reduced. Grade 303Se is not
readily available in Australia.

Chemical Composition of 303
Welding of 303 Stainless is not recommended however if this is if
unavoidable then use 308L or 309 for electrodes. 303 must be
annealed for optimal corrosion protection.
For optimal annealing heat to 1010-1120°C (1850-2048°F) and cool
rapidly with air or water.
EN 1.4305 303 stainless steel cannot be hardened by thermal
