Lastek 804

High corrosion resistance, easy to polish

This electrode exhibits very high corrosion resistance, and deposits are easily polished.

It is an extra low carbon alloy, designed for welding 18/8 Mo austenitic stainless steels.

Very high and rapid deposition rate, excellent weld pool control, deposited beads are finely rippled and have a very aesthetic profile.

Heat input is very low, 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 801 to weld stabilized stainless steels that are used at higher working temperatures.
