Description
Caractéristiques :
LKE-9018-B3 is an iron powder low hydrogen type electrode for low alloy heat resistance steel. The weld metal contains 2.25%Cr-1%Mo which the service temperature is at 550°C. Good creep rupture strength also can be obtained at high temperature.
Applications :
It is suitable for welding of piping steels (STPA24, A335-P22), boilers (STBA24), heat exchanger pipes (A182-F22, A336-F22)
Notes sur l'utilisation :
1.Dry the electrodes at 350-400°C for 60 minutes before use.
2.Keep the arc as short as possible.
