OK Flux 10.61 – High basic fluxfor DC weldingOK Flux 10.61 is anagglomerated, high-basic fluxfor submerged arc welding. It isused for single and multi-runbutt welding when demands onimpact toughness values arehigh. This is a good alternativeto other high basic fluxes whenwelding is done with single wireDC+.The flux alloys very little Si andMn to the weld metal and thusit is well suited for welding ofunlimited plate thicknesses.OK Flux 10.61 is used ingeneral construction, pressurevessel construction, powergeneration and transportindustries.Classification flux Basicity index Density Grain sizeEN 760: SA FB 1 65 DC 2.6 ~ 1.1 kg/dm 3 0.2 - 1.6 mmSlag type Polarity Alloy transferFluoride-basic DC+ Slightly Si and no Mn alloyingFlux consumptionkg flux / kg wireVoltage DC+26 0.730 1.034 1.338 1.6Classification1,00,80,60,40,20,0-0,2% Si pick-upfrom flux% Si in wire450 A750 A0,05 0,10 0,15 0,20 0,25 0,30Single wire, ø 4.0 mm, DC+, 30 V, 60 cm/min1,81,41,00,60,2-0,2-0,6-1,0% Mn pick-upfrom flux450 A750 A% Mn in wire0,5 1,0 1,5 2,0WireWeld metalOK Autrod EN / AWS EN / AW AWS / AW AWS / PWHT12.10 S1 / EL12 Not applicable12.22 S2Si / EM12K S 38 4 FB S2Si A5.17: F7A8-EM12K A5.17: F6P8-EM12K12.24 S2Mo; S Mo / EA2 S 42 2 FB S2Mo A5.23: F7A4-EA2-A2 A5.23: F7P2-EA2-A212.32 S3Si / EH12K S 42 5 FB S3Si A5.17: F7A6-EH12K A5.17: F7P8-EH12K12.40 S4 / EH14 S 46 3 FB S4 A5.17: F7A6-EH14 A5.17: F7P6-EH1413.10 SC S CrMo1 / EB2R A5.23: F8P2-EB2R-B213.20 SC S CrMo2 / EB3R A5.23: F8P0-EB3R-B3OK Tubrod15.24S A5.23: F7P8-EC-GApprovalsABS BV DNV GL LR TÜV DB CEOK Flux 10.61 x xwith OK Autrod12.10 x x x12.22 x12.24 x x12.32 x13.10 SC x x x13.20 SC xTypical weld metal chemical composition (%), DC+C Si Mn Cr Ni Mo OtherWith OK Autrod12.10 0.07 0.1 0.512.22 0.08 0.3 1.012.24 0.06 0.2 1.0 0.512.32 0.09 0.3 1.412.40 0.08 0.2 1.813.10 SC 0.08 0.3 0.7 1.1 0.513.20 SC 0.08 0.3 0.6 2.0 0.9with OK Tubrod15.24S 0.05 0.4 1.6 0.824
