Characteristics:
The weld metal of LKE-308L is a rutile electrode for welding low carbon 18Cr-8Ni stainless steel. LKE-308L contains low carbon to avoid carbide precipitation during welding.
Applications:
It is suitable for welding of stainless steel piping in refinery, oil and gas industries, and chemical plants.
Notes on Usage:
1.Dry the electrodes at 200-250°C for 60 minutes and keep at 100-150°C before use.
2.To make the cooling time as short as possible between 500-800°C to prevent the intergranular corrosion.
3.Clean up the slag with stainless steel brush to prevent impurity.
4.Use small heat input to reduce dilution, prevent cracking and improve impact value
