Lastek 2400

Abrasion and impact

Hard facing electrode with first layer hardness up to 68 HRC on mild steel, depending on the parent metal. The wear facing shows little or no transverse cracking.

Good shock-resistance.

Smooth arc.

Easy to strike.

High hardness at elevated temperatures (up to 600 °C (1100 °F)) – (38-40 HRC)

Specifications & Usage


Recommended for severe wear accompanied by moderate to high impact.

Bone crushers, dredging teeth, feed screws in cement factories (fueller pumps) cement mixers, pulping knives etc.

Hardness: 60-68 HRC

Efficiency 195 %


Remove fatigued or cracked metal with Lastek 1900 or Lastek 1000.

For surfacing more than two layers use Lastek 27 as a base layer and Lastek 2400 to finish.

The electrode must be kept vertical to the work piece in order to obtain the maximum hardness.

Keep amperage as low as possible to avoid dilution with the base metal.
