Böhler FOXcore 2209-T1 E2209T1-4 Duplex Flux-Cored Wire
Description
Rutile duplex flux-cored wire for 22Cr steels in offshore and chemical plant
The Böhler FOXcore 2209-T1 is a rutile duplex stainless flux-cored wire of type T 22 9 3 N L P / E2209T1, classified AWS A5.22 E2209T1-4(1). Böhler Welding specifies it for 22Cr steel grades such as 1.4462 (UNS S31803 and S32205), and for dissimilar joints and weld cladding, designed for offshore, shipyards, chemical tankers, chemical and petrochemical plants and pulp and paper. It has very good resistance to pitting, intergranular and stress corrosion cracking in chloride-containing environments such as seawater, and meets ASTM G48 Methods A, B and E at 77 °F. It is over-alloyed in nickel to promote austenite formation, and ferrite measured with a Fischer Feritescope is 35 to 45 FN. The wire is used in all positions without changing parameters.

Using duplex cored wire correctly
The data sheet advises a backhand (drag) technique with a work angle around 80 degrees on a standard GMAW source with no pulsing, and no post-weld heat treatment except in special cases (solution annealing at 2012 to 2165 °F with water quench). For flat and horizontal positions (1G, 1F and 2F) Böhler suggests FOXcore 2209-T0 instead. Observe the heat-input window, as too little heat input leaves too much ferrite and too much heat input reduces ferrite and toughness. The wire is the cored-wire member of a duplex set that includes the TIG rod and the electrode.

|---|---|---|
| FOXcore 71 RC | AWS A5.20 E71T-1 family | All-position rutile wire for mild steel, 0.045 to 1/16 in. |
| FOXcore 316L-T1 | AWS A5.22 E316LT1-4(1) | 316L stainless, all positions |

Handling and what to confirm
Confirm base grade, plate thickness, ferrite and corrosion-test requirements (ASTM G48 or A923), shielding gas, spool format and class approvals. Only the 0.045 in diameter is on the data sheet, so if another diameter is needed ask before ordering.

About brand
Böhler Welding is the welding consumables brand of voestalpine Böhler Welding, part of the voestalpine group, with a portfolio that covers stick electrodes, TIG rods, solid wires, gas-shielded and self-shielded flux-cored wires and submerged-arc wires and fluxes. The company states more than 100 years of experience. Seven Star LLC, an independent supplier in Muscat, lists Böhler Welding consumables and welding machines, including pipeline electrodes, and sources Böhler Welding consumables for fabricators and pipeline contractors.
Böhler Welding product groups
Beyond the consumables above, Böhler Welding lists strip cladding, wire arc additive manufacturing, metal powders, arc spraying cored wires, ceramic weld backing, brazing consumables and welding automation such as orbital welding and collaborative robots. The pipeline range includes cellulosic FOX CEL electrodes and basic vertical-down FOX BVD electrodes for large-diameter line pipe.
Ordering Böhler Welding consumables: what we need
Give the product name, the AWS or EN classification, the diameter and length, and the packaging you need. For pipeline electrodes also state the pipe grade, wall thickness, welding position and whether sour-service test values are required, because the Böhler Welding data sheets note that some test values are available on request.
