Lastek 807

Joining of - and buffer layers on problem steels

Lastek 807 is a high strength, ductile, crack resistant electrode designed for welding problem steels such as high carbon and crack sensitive tool steels or manganese steel.

Heat resistant up to 850 °C (1560 °F).

Rust proof.

Recommended for hardfacings; High resistance to wear and heavy shocks.

High recovery (160 %).

Specifications & Usage


Joining of highly alloyed and difficult to weld steel.

Surfacing and repair of excavators buckets.

Joining and surfacing of rails and steel with 14 % manganese.

Cushion layer for hard facings.

Surfacing of rollers, crane-wheels, …

Hardness: +/- 200 HB as welded and +/- 450 HB after workhardening.


Keep the arc as short as possible. Electrode position almost 90° to the workpiece.

For welding 14% Mn-steel, keep the temperature of the workpiece below 350 °C (660 °F)
