Stainless steel electrode CHS007 (A007) comply with: GB / T983 E308L-15 AWS A5.4 E308L-15 Description: CHS007 is a basic drug skin type of low carbon stainless steel electrode, the higher its basicity, the carbon content of weld metal ≤0.04%, S, P, O impurity content is low, so it is good crack resistance. The electrode using DC reverse, all-position welding performance and excellent operability. Slight wobble when required welding electrodes, in order to facilitate and reduce the excessive droplet magnetic blow. Uses: Used for welding low carbon 022Cr19Ni10 stainless steel structure. It can also be used 06Cr18Ni11Ti temperature below 300 ℃ corrosion-resistant stainless steel structure. Mainly used in the manufacture of synthetic fibers, fertilizers, oil and other equipment.
