Fluxofil 25 Oerlikon Flux Cored Wire

Oerlikon Fluxofil 25 Flux-cored Wire

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

Areas of application
- **Boiler and pressure vessel construction** (temperatures up to 530 °C)  
- **Pipeline construction** in the chemical and energy industries  
- **General fabrication** 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 all-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  

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