Fluxofil 25 Oerlikon Flux Cored Wire

Flux-cored wire Oerlikon Fluxofil 25

FLUXOFIL 25 is a rutile-based, fast-freezing flux-cored electrode specially developed for gas metal arc welding (MIG/MAG) of non-alloy and low-alloy steels. The electrode has a seamless construction and is suitable for all welding positions in spray arc. It is particularly optimized for use in boiler, vessel, and pipeline construction at operating temperatures up to 530 °C – a typical application is 16Mo3 steel [1].

Areas of application
- **Boiler and vessel construction** (temperatures up to 530 °C)
- **Pipeline construction** in the chemical and energy industries
- **General manufacturing** of heat-resistant steels (S 235-S 460, 16Mo3)

Welding positions:

All (PA, PB, PC, PD, PE, PF) |

Polarity:

DC +

* **Storage:** store dry, do not re-dry.
* **Approvals:** TÜV-tested, EN ISO 17634-A, AWS A5.36.

Mechanical properties of the pure weld metal (untreated)
- **Yield strength:** ≥ 490 MPa
- **Tensile strength:** 550-650 MPa (depending on material)
- **Elongation:** ≥ 22 %
- **Impact energy (ISO-V, 20 °C):** ≥ 70 J

After heat treatment (620 °C × 1 h), the yield strength remains ≥ 470 MPa and the tensile strength 550-690 MPa, while the other values remain unchanged [1].
