The deposited metal has excellent crack-resistance and oxidation-resistance. AC/DC. It has excellent welding performance. In order to increase the crack-resistance and corrosion-resistance of the deposited metal, the Mo content is increased properly, 1% higher than that of GB/T983-1995 E309-16. The other elements all accord with the international standard. Application: Used for welding the same types of stainless steel, stainless steel lining, dissimilar steel (Cr19Ni9 is the same as low-carbon steel), high-chrome steel, high-manganese steel, etc. Instruction: 1. The electrodes should be baked under 200-250º C for an hour before welding. 2. Direct current had better be used and the current should not be too strong.
