UTP UP FX 680 is a neutral, fused sub-arc welding flux of the calcium-silikate-type for
joining and hardfacing of low-alloyed heat-resistant steels.
It is a light basic type, has neutral metallurgical behaviour and provides excellent slag
detachability. It is designed for use under direct current.
Chemical composition of the flux (guiding values) in %
CaF2 CaO + MgO Al2O3 SiO2

Properties
• Basicity grade (according to Boniszewski) 1,3
• Grain size 0,1 – 1,6 mm (Tyler: 10 x 150)
• Flux consumption ~ 1 (kg flux / kg wire)
• If stored properly / for first use, the flux can be used without redrying directly from the
