AWS A5.4 E309-16 stainless steel welding electrode

Applications and Features :

• Weld metal is 23.5%Cr-13%Ni.

• The proper ferrite contents in the weld metal can prevent crack at high temperature.

• It is suitable for welding AISI 309S and dissimilar metals (mild steel and stainless steel).

• It is used as the buttering layer when welding dissimilar metals, which provides excellent performance for corrosion resistant surface between mild steel and hard-to-weld steel.
