Description:
CHS002
is a
lime-titanium type welding rod for extra-low carbon stainless steels. The
weld metal shows very good resistance to inter-crystal corrosion for the
carbon content in it is
≤0.04%.
All positions welding are good. Welding of extra-low carbon stainless steel
00Cr19Ni10(e.g.304L). Also welding of 0Cr18Ni10Ti stainless steel
structures, which working conditions need to be resistance corrosion and
temperature is below 300℃.
Mainly be used in equipments of synthetic funicle, fertilizer, petroleum &
chemical industry etc. Before welding, the weld metal must be clear away
impurities, such as oil, rust, moisture etc., and the rod should be baked at
the temperature from 300℃
to 350℃
for 1 hour. In welding, should use small current and short arc, and swaying
broad less than 2.5 times of diameter of the core rod is better.
