LKE-308 Characteristics and Applications:
The weld metal of LKE-308 is austenite limited + δ-ferrite structure (19%Cr-9%Ni). It is suitable for the welding of AISI-304, 304 steel, AISI-301 steel and AISI-302 steel in all positions.
Notes on Usage: 1.Dry the electrodes at 200-250℃ for 60 minutes and keep at 100-150℃ before use. 2.To make the cooling time as short as possible between 500-800℃ 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.
