Austenitic SUS309S stainless steel Process Approach

SUS309S stainless steel (UNS S30900 / S30908) austenitic stainless steel is mainly used in high temperature environments. Its high chromium content and nickel content ensures good corrosion resistance and oxidation resistance. Compared with the 304 austenitic alloy, which at room temperature strength to be a little higher.

Chemical Composition of SUS309S

Mechanical Property of SUS309S

SUS309S Process Approach:
The main reason for annealing these alloys is to produce a fine recrystallized structure, to achieve uniform grain size, the decomposition of harmful chromium carbide precipitates. To ensure complete annealing, the material must be placed 2050-2150 ° F (1120-1175 ° C) within a temperature range of time required per inch of thickness of about 30 minutes. This is just a general approach. Special circumstances may require special treatment. After appropriate annealing, these grades are primarily austenitic at room temperature, a small amount of ferrite may also be present.
