Grade 303Cu Stainless Steel Round Bar Hot Rolled / Cold Drawn SS
Bars 303 Stainless Steel Bar
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 stainless steel
Features of 303 stainless steel
- Relatively okay corrosion resistance, however because of presence
of sulfur, considerably less resilient compared to grade 304.
- 303 Stainless Steel is not affected and cannot be hardened by
Applications of 15-5ph stainless steel
303 is the perfect grade stainless steel to be used in machining
applications. Typically 303 can be found used in shafts, nuts,
bolts, with gears, in aircraft fittings316L Grade Stainless Steel
is one of the more common austenitic stainless steels.
- Nuts and Bolts
- Aircraft Fittings
- Electrical Switchgear Components
- In general any component that is heavily machined and where the
corrosion resistance and fabrication properties of 303 are viable.
