ASTM A269 TP347 stainless steel pipes are widely used in aviation, petrochemical, food, papermaking and other industries.
ASTM A269 TP347 steel pipes have good resistance to intergranular corrosion, which makes it have a long service life in high temperature and corrosive environments. Physical constants include melting point (1398-1427 degree ), density (7.9g/cm³), specific heat capacity (500J/kg·K), etc.
ASTM A269 TP347 stainless steel round pipes can be welded with ER347 welding wire and have stable oxidation resistance in air at 750-800 degree .
