Lastek 803

Welding 18/8 austenitic stainless steel with low carbon content

Electrode with a quiet arc and excellent weld pool control.

Deposited beads are finely rippled and have a very aesthetic profile.

Heat input is very low and slag release is easy.

Provides porosity free deposits, with a glossy finish.

The deposited welds resist intergranular corrosion up to 350°C (662°F).

Use Lastek 800 to weld stabilized stainless steels that are used at higher working temperatures.
