Description:
CHS29.9
is a
lime-titanium type duplex stainless steel electrode for welding dissimilar
steels, Cr29Ni9 cast steels as well as problem steels. Before welding, the
weld metal must be clear away impurities, such as oil, rust, moisture etc.,
and the electrode should be baked at the temperature from 300℃
to 350℃
for 1 hour.
