FCW DCO S

Cored wire for submerged arc hardfacing

Product description

-Cored wire for submerged arc cladding

The deposited alloy, alloyed with chromium, cobalt and molybdenum, resists wear caused by cavitation, erosion, metal-to-metal friction and fatigue. It retains these properties at high temperatures, and also offers a degree of corrosion resistance.

Why choose this cored wire?

FCW DCO-O cored wire is mainly used for hardfacing applications, where parts are subjected to extreme conditions of wear and heat. Here’s why it’s used:

Technical advantages :

High resistance to metal-to-metal wear
→ Perfect for parts in constant friction without the presence of abrasive particles.

Good resistance to corrosion and oxidation
→ Effective even in chemical environments or aggressive atmospheres.

High-temperature resistance (up to ~550°C)
→ Suitable for thermally demanding environments, such as forging tools or parts exposed to thermal cycling.

Low cracking
→ Thanks to its specific metallurgical structure (cobalt-chromium alloy), it enables robust, long-lasting deposits.
