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.
