304 stainless steel is easy to machine and very widely used. Due to the wide usage, 304 stainless steel is usually cheaper than other grades when purchased in the unmachined form. It should always be remembered though, that finished machined parts have their own input costs. It can’t be assumed that two similar sized shafts will be cheaper in 304 stainless than in 316 stainless simply because the base material cost is cheaper.
The main component of the steel is Fe (Iron) with the addition of the elements shown in the following chart
|Max. % Chemical Composition|
|0.08||1.0||2.0||0.045||0.03||18.0 to 20.0||-||8.0 to 10.5|
For slightly less corrosion resistance but better machinability see 303 Grade
For higher resistance to pitting and crevice corrosion in chloride environments but lower machinability see 316 Grade
For better machinability but lower corrosion resistance, or if hardening by heat treatment is required see 416 Grade
