Lastek 27

Multilayer hard facing

The air hardening deposit of Lastek 27 is resistant to abrasion and impact.

Many layers can be built up without cracking.

Nevertheless, the wear resistance is much better than ordinary martensitic electrodes of the chromium – carbon type.

Also at elevated temperature applications (up to 550°C – 1020°F), Lastek 27 can be used.

Specifications & Usage


Soil abrasion (bucket edges, sand pump casings, bulldozer teeth).

Metal shears, stamping dies, mixer blades, ripper teeth, crusher jaws.

Hardness: 58-62 Rc.


Electrode position: almost vertical to the work piece.

Use a very short arc and keep the amperage as low as possible, to avoid too much dilution with the base material.

To obtain the maximum hardness on mild steel, apply at least 3 layers.
