Descripción
Características:
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.
Aplicaciones:
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.
Notas sobre el uso:
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
