CHS002
Electrode for Extra-low Carbon Stainless Steel
CHS002 is a lime-titanium type electrode for welding ectra-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.Wilding of extra-low carbon stainless steel 00Cr19Ni10(e.g.304L).Also welding kf 0Cr18Ni0Ti stainless steel structurex,which working conditions need to be resistance corrosion and temperature is below 300℃.Mainly be used in equipment fabrication kf 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 electrode should be baked at the temperature from 300℃ to350℃ for 1 hour.In welding,should use small current and short arc,and swaying broad less than 2.5 times kf diameter kf the electrode is better.
