347H stainless steel round pipe is a very stable stainless steel. It can still maintain good resistance to intergranular corrosion under the condition of temperature reaching 427-816°C and chromium carbide precipitation.
ASTM A312 TP347 steel pipe has good corrosion resistance and pitting resistance to a variety of inorganic acids, organic acids, alkalis and salts.
SS 347 Thin Wall Pipe is not only used for large boiler superheater tubes, reheater tubes, steam pipes and petrochemical heat exchangers, but also can be used as pitting corrosion resistant materials. It is also used in nuclear power, precision electronics, architectural decoration and other fields.
