Applications and Features

( 1 )       High molybdenum content provides good stress, pitting and crevice corrosion resistance.

( 2 ) Ideal for welding materials of similar composition, such as Inconel 601, 625, 718 and Alloy 20.

( 3 ) Suited for welding pipeline and reactor components in power generation industry, high temperature service in engineering applications such as furnace equipment, petrochemical plants, and marine/offshore environments.
