Applications and Features :
Weld metal is austenite structure with 25%Cr-20%Ni.
It has superior corrosion resistance and strength at 1000°C due to more Ni and Cr content.
It is ideal for welding AISI 310S steel and dissimilar metals (carbon steel, Cr-Mo steel and stainless steel).
It is also suitable for low temperature and non-magnetic applications.
