Isoarc 347 is primarily intended for high temperature service or application that should be heat treated. However the corrosion resistance corresponds to that of 308H, i.e good resistance to general corrosion. Electrode for welding stabilized austenitic stainless steels such as AISI 347 and 321
Isoarc 347 can be used for cladding ,which normally requires stress relieving at around 590°C, Such heat treatment will lower ductility at room temperature. Always consult expertise before performing post-weld heat treatment.
If moist re-dry at 300°C for 2 hours.
