描述
特性：
The weld metal of LKE-309 contains more Cr, Ni than LKE-308. 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.
應用：
It is suitable for welding of stainless steel piping in refineries and chemical plants.
使用注意事項：
1. Dry the electrodes at 200-250oC for 60 minutes and keep at 100-150oC before use.
2. Use lower currents for dissimilar metals welding.
