Lastek 8000

Joining carbon steel to stainless steel

Electrode with 14% ferrite, recommended for joining steel to stainless steel.

Joining and surfacing carbon steel, spring steel, tool steel, manganese steel, stainless steel (AISI 304, 316, 1.4401, 1.4435).

Heat resistant up to 900 °C (1650 °F); Corrosion and wear resistant; High recovery (165 %).

The electrode does not become red-hot and can be entirely used even at high current.

L8000 welds with a very smooth arc and has a self releasing slag.

For carbon steel to stainless steel joints, the deposit is free of martensite up to dilution levels of 13%.

Specifications & Usage


Welding of flanges to stainless steel tubes.

Surfacing track links.

Welding wear resistant plates of unknown analysis.

Applying stainless protective layers on mild steel.

Base layer for hard facings.


Keep a short arc and use a low current.

For welding stainless steel, the coating must not be damaged and it is recommended to return over the starting point of the bead.

When the electrodes have taken up humidity, dry them at 250°C (480°F) for 2 hours.

For optimum corrosion resistance on AISI 316L, use Lastek 804.
