Applications and Features :
Weld metal is low carbon 18%Cr-12%Ni-2%Mo.
Its extra low carbon content prevents intergranular corrosion.
It provides good strength at high temperature and post weld heat treatment is not required.
It is suitable for welding critical chemical vessels that require low temperature impact property, such as liquid natural gas tank.
