Lastifil 85

Joining difficult to weld steel - highest strength

Solid welding wire for joining dissimilar steel types (stainless steel to carbon steel) and for refacings.

Suitable for welding steel with a high carbon content.

An elevated delta ferrite content in an austenitic structure assures a very high resistance against hot cracking.

Suitable for welding manganese steel, armour steel, spring steel. Refacings that harden by impact load.

Oxidation resistant up to 1150 °C (2100 °F).

Specifications & Usage


Joining wearplates.

Dissimilar welding (stainless steel to steel).

Crack-resistant underlayers for hardfacings.

Refacings where good corrosion resistance or friction resistance is expected and where abrasion resistance is less important.

Welding or repairing cast steel with a high chromium content (1.4762, 1.4085 aso).


Joining difficult to weld steel: in function of the chemical composition and the workpiece section, preheating and slowly cooling down can be necessary.

Avoid any heattreatment at temperatures between 550 °C (1020 °F) and 850 °C (1560 °F) and prevent that heavy welds remain too long in this temperature zone.
