Application

It is mainly used for the welding of similar duplex stainless steel in offshore oil, natural gas and petrochemical industry, but also can be used for the welding of low alloy steel and carbon steel with duplex stainless steel, such as 022Cr25Ni7Mo4N.

Characteristics

JL-E2594-16 is an ultra-low carbon duplex stainless steel electrode with rutile type flux. It can be used in both AC and DC welding, and can be welded in all positions. The welding process performance is excellent, and the deposited metal has good heat resistance, corrosion resistance and crack resistance.

Note

The electrode must be baked at 300-350 ℃ for 1 hour before welding, and used immediately after baking.

Rust, oil, water and other impurities on the welding parts must be removed before welding.

It is recommended to use a DC power supply, because the welding depth is shallow with AC welding, and the current should not be too high to avoid cracking of the coating.
