Other Specification:

FOR STAINLESS STEEL

I. APPLICATIONS:

For welding 321 and 347. Niobium stabilized reduces chance of chromium carbide precipitation and consuqueent intergranular corrosion.  

II. DESCRIPTIONS:

NT-347 is the welding material which has the composition of 19%Cr-9%Ni-Nb. As Nb is added, its resistibility to intergranular corrosion in an as-welded state is good. Besides, it has high strength at elevated temperature. NT-347 is used for welding of SUS321 and SUS347.
