GEEFLUX 541 X GEESAW EF5

CLASSIFICATION: AWS/ASME SFA-5.23     F11A5EF5 – F5

Applications , Properties : Medium – alloy solid electrode designed for submerged – arc welding of high – strength fine grain structural steels in conjunction with highly basis flux – Geeflux 541. Weld metal meets requirements as to mechanical properties in the as-welded and stress – relieved condition. Robake welding flux for 3h at 350 – 400˚C before use.

Materials :

Heat treated fine grain structural steels, e.g. A 517 Gr F, N-A-XTRA 63,N-A-XTRA 70,T 1,T 1A,T 1 B and others.

Mechanical properties depend upon cooling conditions. They are influenced by heat input and interpass temperature. Optimal results will be obtained at a heat input of E ≤ 15 kJ/cm. Interpass temperature should not significantly exceed 150 °C. Steel manufacturer's specifications for welding thinner plates should be observed.
