EN 14700: E Fe 9

Recovery: 120%

Current: = (+) / ~

C: 0,8 – 1,2

Mn: 12,0 – 14,0

Ni: 2,5 – 3,5

Basic coated electrode for overlays on maganese hard steel like dredger teeth, crusher jaws etc. that is parts mainly subject to impact load.

Hardness of the welding deposits 200 – 250 HB, which increases to 450 – 550 HB by strian hardening, leading to much better wear-resistance.

If possible, welding should be without great head input. It is recommended to interrupt the welding process from time to time in order to cool the overlayed welding deposit with water.

H: 200 – 250 HB

Strainhardened:
450 -550 HB
