CHS29.9
CHS29.9 is a lime-titanium type stainless steel electrode for welding dissimilar steels,Cr29Ni9 cast 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 hours.
