Applications

AWS A 5.9 ER347 .TIG Welding of 18%Cr-8%Ni-Nb(STS 347) and 18%Cr-8%Ni-Ti(STS 321) stainless steel

Characteristics on Usage

As the weld metal contains ferrite, its resistance to crack is good.
Bead appearance and weldability are good.
AWS A 5.9 ER347  has stabilizing element (Nb) thus providing good integranular

corrosion resistance and better heat resistance.
Due to high creep strength at high temperature, suitable for the
welding of boiler and gas turbine.
