OVERVIEW

High-Performance Repair for Heavy Industry

When you are tasked with repairing massive hydro turbine runners, valve bodies, or high-pressure pumps, speed and quality are everything. The Hobart Fabco 410NiMoT1 is your go-to solution for welding 410NiMo and CA6NM type steels. Unlike stick electrodes that require frequent stops for rod changes, this 1/16" flux-cored wire allows for continuous welding with high deposition rates, helping you get critical equipment back online faster. It delivers a smooth, stable arc with excellent bead contour, ensuring that your buildup requires less grinding and finishing work.

Welders will appreciate the operator-friendly characteristics of the Fabco series. The slag system is designed for easy detachment, often curling up on its own as the weld cools, which saves valuable time during multi-pass operations. The wire runs smoothly on standard CV (Constant Voltage) power sources and feeds reliably through heavy-duty MIG guns. Whether you are running straight CO2 for deep penetration and cost savings, or an Argon blend for a smoother arc, this wire performs consistently. It is specifically engineered to resist the cracking issues often associated with martensitic stainless steels, giving you confidence in every pass.

This 33 lb spool comes in a vacuum-sealed package, guaranteeing that the wire is factory-fresh when you open it. This is vital for preventing porosity and hydrogen-induced cracking in sensitive high-strength applications. If your shop handles heavy equipment repair, power generation maintenance, or specialized casting repairs, keeping Hobart Fabco 410NiMoT1 on hand ensures you are ready for the toughest stainless jobs.

FAQ

You can use either 100% CO2 or a mixture of 75% Argon and 25% CO2. The Argon mix typically provides a smoother arc and less spatter, while CO2 provides deeper penetration.

It meets the requirements for AWS A5.22, classifications E410NiMoT1-1 and E410NiMoT1-4.

Yes, because it welds air-hardening martensitic stainless steels, preheat and interpass temperature control (typically 300°F - 500°F) are usually required to prevent cracking.

The 1/16" diameter is generally recommended for Flat and Horizontal positions due to the high fluidity of the weld pool. Smaller diameters might be needed for out-of-position work.

It is primarily used for welding ASTM CA6NM castings and repairing hydro turbine components subject to cavitation and erosion.

PWHT is highly recommended (typically around 1100°F - 1150°F) to temper the martensitic structure and improve toughness and ductility.

Knurled drive rolls are recommended for flux-cored wires to ensure positive feeding without crushing the wire.

If not used immediately, the spool should be stored in a dry, low-humidity environment or a rod oven adapted for spools to prevent moisture pickup.
