Product name:KMS-309LSi
 
Classification:ER309LSi
 
 

Applications and Features

 

( 1 ) Weld metal is austenitic structure with 23%Cr-12%Ni.

( 2 ) High silicon level for increased puddle fluidity and toe wetting.

( 3 ) 0.02% carbon content increases resistance to intergranular corrosion.

( 4 ) Used for welding dissimilar materials such as mild steel to stainless steel, as well as for a barrier layer in stainless overlays.
