Description
Characteristics:
The weld metal of LKE-317L is low carbon 19%Cr-12%Ni-3%Mo stainless steel which contains proper quantity of ferrite. Good corrosion resistance to sulfuric acid and organic acid can be obtained due to its Mo content. It is suitable for welding of chemical vessels and AISI 317L steel.
Applications:
It is suitable for welding of stainless steel piping and vessels in oil and gas industry, refineries and chemicals plants.
Notes on Usage:
1.Dry the electrodes at 200-250°C for 60 minutes and keep at 100-150°C before use.
2.Use lower currents and keep the arc as short as possible.
