Characteristics:<\/strong><\/p>\n

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.<\/p>\n

Applications:<\/strong><\/p>\n

It is excellent for the welding of dissimilar metals, cladding steel and steels with high hardenability.<\/p>\n

Notes on Usage:<\/strong><\/p>\n

1.Dry the electrodes at 200-250 \u00b0C for 60 minutes and keep at 100-150 \u00b0C before use.
\n2.Use lower currents for dissimilar metals welding. Keep the interpass temperature below 150 \u00b0C<\/p>\n
