E309-16

According with GB E309-16
Corresponding with AWS E309-16

Introduction: E309-16 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. We add about 1% more Mo materials in order to increase the crack-resistance and corrosion-resistance of the deposited metal. All other elements keep equal with any international standard.

Applications: 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.
