Why choose this cored wire?
FCW M CrMo2 is a low-alloy steel used in high-pressure, high-temperature applications and demanding environments. Metal-Cored flux-cored wire is a technically and economically efficient solution for guaranteeing high-quality, reliable, standard-compliant welds.
The advantages of FCW M CrMo2 cored wire:
-Maximum productivity: thanks to its high deposition rate and fast welding speed, Metalcored wire is ideal for long weld lengths and intensive production.
-Excellent welding quality: stable arc, smooth bead, low spatter and excellent wetting.
-Composition adapted to CrMo2: the wire deposits a metal with good chromium and molybdenum contents, ensuring temperature resistance and creep resistance.
– Less rework and fewer defects: defects such as porosities, inclusions or cracks are reduced thanks to the wire formulation.
-Low fume content: cleaner than basic or rutile cored wire, it improves working conditions for welders.
