It has the highest hardness among the cobalt-based electrodes.

It is used for joining steels that are difficult to weld such as armor steel and to form a buffer layer before hardfacing applications.

It is used for hardfacing of high alloy steels, hot work steels, self-hardening steels, high manganese steels and nickel alloys.

It is especially used for hardfacing of manganese steels, low and high alloy steels, carbon steels and Ni-Hard materials (with special welding method).

Kobatek 550 deposits a Cr/Mo alloyed, medium carbon, low-alloyed steel hard-surfacing weld metal, that is wear resistant under conditions of high pressure and impact combined with mild abrasion. It is particularly suited for surfacing cold cutting tools and for re-building manganese hard steel.

Used for hardfacing of high alloy steels, hot work steels, self-hardening steels, high manganese steels and nickel alloys.

It has high resistance to intergranular corrosion under general corrosion conditions.

It is used for hardfacing of high alloy steels, hot work steels, self-hardening steels, high manganese steels and nickel alloys.

It is used in joining of nickel-based alloys, dissimilar materials, difficult to weld steels and for buffering before hardfacing applications.

It is used for hardfacing of high alloy steels, hot work steels, self-hardening steels, high manganese steels and nickel alloys.
