Geeflux 541 is a fluoride-basic flux with high basicity and low impurity levels such as P and S. As a result of low oxygen levels in the weld deposits uniform mechanical properties with high toughness values a low temperature are achieved. Because of the almost neutral slag-reactions the chemical analysis of the weld metal can be excellently controlled through the selection of appropriate wire electrodes.

CHARACTERISTIC CHEMICAL CONSTITUENTS
Low hydrogen levels after redrying according to the recommendation on the flux labels and optimum
mechanical properties, whilst observing recommended heat control, enable the welding :
• Tick-walled constructional steels with yield strengths of upto 420 MPa.
• Off-Shore applications upto 460 MPa yield strengths on steels such as BS 4360-Grade 50 D and S355 2G3 according to DIN EN 10025 (previous designation St 52-3N).
• Fine grain structural steels for low temperature requirements with impact toughness at -60°C or below.
• High tensile fine grain steels such as S690QL1 and N-A-XTRA 70.
