    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
