Description
Characteristics:
LKE-410 is used to give a martensitic weld metal of 13%Cr type for welding and building up of ferritic-martensitic steels. With good oxidization and corrosion resistance.
Applications:
It is suitable for welding of the AISI 410 and AISI 420.Typical applications include constructions exposed to aggressive sulphuric gases in refineries, oil and gas industries and chemical plants.
Notes on Usage:
1.Dry the electrodes at 250-300°C for 60 minutes and keep at 100-150°C before use.
2.Use lower currents and keep the arc as short as possible.
3.Preheat at 200-250°C, interpass temperature 180-250°C and post-weld heat treatment at 700-800°C
