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).
Recommended for hardfacings; High resistance to wear and heavy shocks.
High recovery (160 %).
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)
