Lastifil 807

Joining difficult to weld steel - highest toughness

Joining highly alloyed and difficult to weld steel.

Very tough, wear resistant refacings, resistant against heavy shocks, corrosion and rust.

Work hardens under impact load.

Crack resistant base layer for hard facings.

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

Specifications & Usage


Welding armour steel, wear resistant chromium steels (3CR12 for example), manganese steel (12% Mn), joining stainless steel to carbon steel.

Refacing rails, frogs, clutches, crane wheels.

Universal welding wire for maintenance and repair.


Joining difficult to weld steel: in function of the chemical analysis and the work piece thickness, preheating or cooling down slowly can be necessary.

Manganese steel (12%) is welded without preheat (max. 350° (660°F) interpass temperature).
