303 Stainless Round Bar Stock

303 Stainless has excellent machinability characteristics.

303 Stainless

The austenitic stainless steel grade 303 is the most machinable of all kinds, thanks to its low carbon content.

Because of the inclusion of Sulfur in the steel composition, 303 Stainless has excellent machinability characteristics. Since Sulfur improves machining, it also negatively corrosion resistance and toughness to a minor extent. A lower corrosion resistance rating than type 304 is achieved using type 303 steel. Toughness is excellent, as it is with the other austenitic grades.

Machinability and other Processes

Although 303 Stainless is not generally recommended to weld, it is still possible with some difficulty. After welding, the part should be annealed to re-dissolve any precipitated carbides. Meanwhile, its high machining rates can be achieved in the annealed condition when the hardness of the material is in the range of 200-240 Brinell.

Applications

It is undoubtedly a big help in many industries because of its incredible characteristics. Aircraft fittings, bolts, bushings, gears, nuts, and shafts are just a few of the many applications of 303 Stainless.
