DESCRIPTION

NS-680 is a lime-titania type stainless electrode depositing weld metal of 29%Cr-9%Ni.

As the weld metal contains large quantity of ferrite, its crack resistibility is good. It is used

for welding dissimilar metals and underlaying welding of hard surfacing.

INSTRUCTIONS FOR WELDING

1.Choose the welding current as low as possible to prevent cracking of plate.

2.In the case of welding high alley steel such is tool steels, it is necessary to preheat the

plate over 200 ^๐C.
