AWS A5.4 E309-16
Description:
AWS E308-16 A302 is a kind of Cr23Ni13 stainless steel electrode with lime-titania type coating. 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.
