TP304LN is an austenitic stainless steel with low carbon content alloyed with nitrogen.
Corrosion Resistance
TP304LN stainless has good resistance to atomosperic resistance. Like
TP304L, TP304LN is resistant to wide variety if inorganic chemicals as
well as nitric acid.
TP304LN has good intergranular corrosion in the as-annealed and
as-welded condition due to its low carbon content. Some intergranular
attack may occur in the hot rolled unannealed condition.
Application
UNS S30453
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.
