LASTEK 85 small

Lastek 85

Joining dissimilar metals and difficult to weld steels

EN ISO 14700 (E Fe11)
A5.4 (E 312-16)

General description:

Highly alloyed electrode for joining and surfacing tool steel, spring steel, manganese steel, carbon steel and all difficult to weld steels and dissimilar metals. The deposit has exceptional tensile strength and resistance to cracking.
Oxidation resistant up to 900°C. Even on dirty metal, porous-free welds can be obtained. Stable arc, almost no spatter. Smooth welds, without undercut.

Typical applications:

Joining of broken tools and dies, cast steel, abrasion resistant steel. Copper and carbon steel to stainless steel. Repair of hydraulic rams, bulldozer buckets and teeth, gears. The work hardening characteristics and the high chromium content make Lastek 85 suitable for surfacing on rails and bearing areas, on plastic extrusion tools and cutting edges.

Typical chemical composition of all-weld-metal:

Tips:

Electrode to be held almost at 90° to the work piece with shortest possible arc. Allow each weld bead to cool slightly before making a further deposit. On problem steels, cover the welded area with insulating material in order to avoid a rapid cooling.
