Description:
CHS002 is a  covered electrode with titanium-calcium type coating for welding extra-low carbon stainless steels. The weld metal shows very good resistance to inter-crystalline corrosion for the carbon content in it is <= 0.04%. The arc stability is marvelous when AC is used though both AC and DC are suitable.  All positions welding are good, arc is smooth, spatter is small, surface of weld is looked well, and the coating flux of electrode is stronger.  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 250^oC to 300^oC for 1 hour.  In welding, should use small current and short arc, and swaying broad less than 2.5 times of diameter of the electrode is better.
 

Applications:
Welding of extra-low carbon Cr18Ni9 stainless steel, Also welding of 0Cr18Ni9Ti stainless steel structures, which working conditions need to be resistance corrosion and temperature is below 300^oC.  Mainly be used in equipment fabrication of synthetic fiber, fertilizer, petroleum & chemical industry etc.
