Lastek 262 E

Rubber, paper and plastics

Cobalt base electrode for friction and corrosion resistant hardfacings.

Excellent resistance to high temperatures (up to 1000 °C) (1830 °F).

Machinable with hard metal tools.

Good shock resistance.

Resistance to nitric and acetic acid, superheated steam, flue gases, petroleum and plastics.

Specifications & Usage


Machine-parts for the manufacturing process of paper and plastics and wood.

Axles and bearings of centrifugal pumps, dies.

Hardness: 47 - 53 HRC.

Hot hardness: approx. 34 HRC @ 600 °C (1110 °F).


Remove all rust and dirt.

Sharp edges must be rounded for optimum adhesion.

The arc should be short to avoid too much dilution with the base metal.

On crack sensitive steels, apply a base layer with Lastek 9066.
