TP304N is an austenitic stainless steel alloyed with nitrogen. Remarkably higher strength at room to high temperatures and higher fatigue strength than that of TP304.


Corrosion Resistance

Corrosion resistance, heat resistance and physical properties similar to those of TP304


Application

Heat exchanger tubing, condenser tubing, pipelines, cooling and heating coils in the chemical, petrochemical, fertiliser, pulp and paper and nuclear power industries, as well as in the production of pharmaceuticals, foods and beverages.
