SSuubb--aarrcc fflluuxx
EN 760-1996 : SA CS 2 DC
EF-200F is a basic and agglomerated flux used for hardfacing in combination with composite wires for
hardfacing such as K-13CrHT.
Typical applications : steel mills concast rolls, valve seats and components subject to wear, fatigue and
corrosion at high temperature.
Outstanding slag release properies and bead profile.
Redry the flux at 250~350℃ for 60 minutes before use
The flux is suitable for single, multi-pass and oscillated welding, using single or twin-wire processes.
Hardness of weld metal may be changed according to base metal, layer height, number of weld pass,
welding condition., etc.
