Hobart FabCO 811B2 .045 Chrome-Moly Flux Core Wire 15kg

Hobart FabCO 811B2: The Pro's Choice for Chrome-Moly

When you are tackling Chrome-Moly pipe or plate, you need a wire that runs smooth and passes X-ray every time. The Hobart FabCO 811B2 .045" flux-cored wire is built exactly for that. Designed for 1.25% Chromium and 0.5% Molybdenum steels, this wire takes the headache out of welding low alloys. Whether you are working on steam pipes in a power plant or fabricating pressure vessels, this wire gives you the control and quality you need to get the job done right the first time.

What makes the FabCO 811B2 stand out is its all-position playability. We know that in the real world, you aren't always welding flat. This wire features a fast-freezing slag that supports the puddle in vertical-up and overhead positions, letting you lay down flat, professional-looking beads without fighting gravity. Plus, the slag releases easily—often peeling off by itself—so you spend less time chipping and grinding and more time welding. It runs on both straight CO2 and Argon/CO2 mixes, giving you the flexibility to use whatever gas is available on the rig or in the shop.

Key Benefits for the Welder:

• Smooth Arc: Stable transfer with minimal spatter keeps your nozzle clean and your vision clear.
• All-Position Ready: conquer out-of-position welds with confidence thanks to the fast-freezing flux system.
• Reliable Packaging: Comes in a 15kg (33lb) vacuum-packed spool to ensure the wire is fresh, dry, and ready to run the moment you crack the seal.

Don't risk your reputation on inferior fillers when working with sensitive Cr-Mo steels. The Hobart FabCO 811B2 delivers the deep penetration and strong mechanical bonds required for high-stress, high-temperature applications. It’s the reliable workhorse for welders who demand performance and consistency in every pass. Grab a spool today and experience the Hobart difference on your next alloy job.
