Applications and Features :
Weld metal is austenite structure with 23%Cr-13%Ni-2%Mo.
It has better strength and corrosion resistance at high temperature than KMS-309 due to its additional Mo content.
It provides good crack resistance due to its moderate ferrite content.
It is suitable for welding dissimilar metals (carbon steel and stainless steel).
