Specification:


ASTM A 269/A 213/A 312 / EN10216-5 /EN ISO 1127 D4/T3/EN 10305 / PED 97/23 EC


Maximum exposure temperature: 850°C / 1560°F


Alloy 347 is an austenitic, niobium, stabilized stainless chromium-nickel steel. It has slightly imposed corrosion resistance over 321 stainless steel in strongly oxidizing environments and is preferable for aqueous and low temperature environments due to its good resistance to inter granular attack. The 347H has high carbon (0.4 to 0.1%) for better high temperature creep properties.


Characteristics:


Excellent resistance to inter granular corrosion due to niobium stabilization


Good resistance to organic aids and salt solutions


Sensitive to pitting and crevice corrosion


Less resistance to stress corrosion crashing by chloride solutions


Market Applications:


Oil refineries


Fires heater tubes


Power plants


Heat exchanges


High chemical process


High temperature stream service
