Böhler FOXcore 71 RC E71T-1 All-Position Flux-Cored Wire
Description
All-position rutile flux-cored wire for mild steel fabrication
The Böhler FOXcore 71 RC is a rutile flux-cored wire with a fast-freezing slag system for all-position welding, listed as AWS A5.20 E71T-1 / T-9 / T-12M-JH8 (with Ar-CO2 gas) and E71T-1 / T-9 / T-12C-JH8 (with CO2). Böhler Welding states that all-position welding is possible with the 0.045 in wire and a single set of parameters, and cites excellent mechanical properties, easy slag removal, low spatter, a finely rippled bead and X-ray quality welds. The data sheet is titled BÖHLER Q 71 RC, the product name under which this wire appears on Böhler’s US data sheet. It is aimed at productivity gains in shipyards and structural shops, where moving between flat, vertical and overhead positions with one setting saves time.

Base materials and gas choice
Böhler lists steels up to 460 MPa (67 ksi) yield strength with M21 shielding gas, including S235JR to S355J2, S275N to S460N, P235GH to P355GH, L245NB to L450MB, shipbuilding steels A, B, D, E and A 32 to E 36, and ASTM A 106 Gr. A to C, A 516 Gr. 55 to 70, A 572 and API 5L Gr. B to X65. The two gas columns above show the trade-off: Ar-CO2 mixed gas gives the higher toughness at -40 °F, while pure CO2 trades some toughness for cheaper gas.

Gas, spool and certificate notes
Confirm the shielding gas and the certificate level in the enquiry, because the classification, toughness and hydrogen level depend on whether the project uses Ar-CO2 or CO2. Also state the diameter, spool or drum format your wire feeder takes, the quantity, the plate grade and thickness, and any class approval (ABS, DNV GL, LR, BV) the contract requires, so that the request can be matched with the approvals printed on the data sheet.
