描述
特点
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.
应用：
It is excellent for the welding of dissimilar metals, cladding steel and steels with high hardenability.
使用说明：
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
