300 Series Stainless Steels

The 300-series group of stainless steels contain 16-30% chromium and from 6-35% nickel. Depending on the composition of these stainless steel castings, the microstructure is predominantly or wholly austenitic and thus unresponsive to heat treatment. The 300 series stainless steels are easily welded and machined but readily work hardened. Generally supplied in the solution annealed condition, these alloys have great corrosion resistance and generally maintain their properties at high temperatures.
