Descripción
Características:
LKE-8016-B8 is a low hydrogen electrode. The weld metal contains 9%Cr-1%Mo.With high tensile strength, good toughness and good heat resistance can be obtained.
Aplicaciones:
It is suitable for welding of 9%Cr-1%Mo steel such as ASTM A387 Gr.9 for refineries, petrochemical and electric power plants including pipe (ASTM A199-T9,A335-P9),drawing steel(A387-9),forging(A182-F9),etc.
Notas sobre el uso:
1.Dry the electrodes at 350-400°C for 60 minutes before use.
2.Do not exceed the range of recommended because over heat input might decrease the impact value.
3.Keep the arc as short as possible.
4.Take the back-step method at the arc starting to prevent blowholes.
5.Preheat the workpiece at 250-350°C and proceed PWHT.
