FCW 1-G

Using Cobalt Grade 1 cored wire (also called Stellite 1 in some contexts) is an excellent choice for hardfacing applications where extreme resistance to wear, corrosion and heat is required. Here’s why this type of wire is preferred:

1. Exceptional resistance to abrasive wear

Cobalt Grade 1 is one of the hardest cobalt-based alloys. It is very rich in chromium and tungsten carbides, making it resistant to both hot and cold abrasion. It is often used for :

-cutting tools,

-parts subjected to repeated friction,

-industrial knives or grinding components.

2. High-temperature stability

It retains its mechanical properties up to around 800-900°C, making it ideal for parts operating under continuous heat (valves, seats, turbine components, etc.).

3. Corrosion and oxidation resistance

Thanks to its cobalt base and alloying elements (Cr, W, etc.), it is naturally resistant to aggressive chemical environments and oxidation, even at high temperatures.

4. Stable metallurgical structure

Cobalt Grade 1 retains a stable structure after deposition, with very little dilution of the base metal. This results in a pure deposit with consistent properties, even after several passes.

5. Why choose cored wire?

Ease of deposition: Cored wire enables faster reloading than with electrode or TIG.

Less spatter, higher yield, and often less cracking than more conventional processes.

Suitable for reloading robots, semi-automatic or automated applications.
