Characteristics:
The weld metal of LKE-312 is a 29%Cr-9Ni% type stainless steel containing large content of ferrite which made it good crack resistance.
Applications:
It is excellent for the welding of dissimilar metals, cladding steel and steels with high hardenability.
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 for dissimilar metals welding. Keep the interpass temperature below 150 °C
