Description
Caractéristiques :
The weld metal of LKE-309L contains more Cr, Ni than LKE-308L. The microstructure containing suitable quantity of ferrite, gives it an excellent resistance to hot cracking. It is suitable for welding of dissimilar metals, hardening alloy steel and steel with poor weldability.
Applications :
It is suitable for welding of stainless steel piping in refineries and chemical plants.
Notes sur l'utilisation :
1.Dry the electrodes at 200-250°C for 60 minutes and keep at 100-150°C before use.
2.Use lower currents for dissimilar metals welding.
