Stainless steel electrode CHS027 (A027) comply with: GB / T983 E316L-15 AWS A5.4 E316L-15 Description: CHS027 is a basic drug skin type of ultra-low carbon stainless steel electrode coating its high alkalinity, carbon content of weld metal ≤0.04%, S, P, O impurity content is low, so it is a good heat resistance, corrosion resistance and 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 urea, synthetic fiber and other equipment and the same type of stainless steel structure, can not also be used for heat treatment after welding chromium stainless steel and composite steel and just so dissimilar.
