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.
