Lastek 85 C

Crack-free welds on problem steels

TIG welding rod for joining difficult to weld steel or for precision repair on dies.

Very high tensile strength, shock resistant and ductile.

Because of the high chromium content, Lastek 85C is oxidation resistant up to 1.150 °C (2.100 °F).

The high ferrite content guarantees crack-free assemblies when welding stainless steel to carbon steel, even at a high dilution.

Specifications & Usage


Joining and refacing high carbon steel, tool steel, spring steel, manganese steel, cast steel.

Wear resistant layers on dies and edges.

Hardness: 260 HB (work hardens up to approx 450 HB).


For refacings with the oxy acetylene flame use flux 802CA
