Lastek 26

High hot hardness

Weld deposit with very high hardness.

Exceptional resistance to abrasion by hard minerals.

Very good shock resistance although very hard.

The hardness remains high up to 600 °C (1112 °F).

Crack and porosity-free deposit.

Self-releasing slag.

Specifications & Usage


Universal use as wear resistant hard facing.

Dredging buckets, grab jaws, pneumatic drills, mixing augers and blades.

Cold and hot working dies and tools, cutting shears, rolls, forging and die cast dies, plough shears.

Hardness after welding: 57-62 HRC.

Hot hardness at 600 °C (1112 °F): 42 HRC.

Hardness after heat treatment (1 hour at 600 °C (1112 °F), air cooling): 61-65 HRC.


Use a short arc and as low as possible amperage to avoid dilution with the base metal.

Electrode position: almost 90° to work piece.

For the surfacing of steel with a hardness lower than 40 HRC, minimum three layers are necessary to obtain the maximum hardness.
