Standard：AWS A5.9, ER309L.
It is 24%Cr-13%Ni stainless steel solid wire shielded by 98%Ar+2%O2.
It can be used for joining 22Cr-12Ni stainless steel, the same type of stainless steel, clad steel and dissimilar steel.
It has good crack resistance, and is suitable for welding martensitic, ferrite stainless steel with poor toughness.
