Thermanit H 347 Si wire electrodes are high-quality welding consumables that were specifically developed for welding austenitic stainless steel types, especially 18/8 steels. These electrodes contain an alloy with high chromium (Cr) and nickel (Ni) content and stabilization with niobium (Nb) and additional silicon (Si), giving them outstanding mechanical properties and excellent resistance to intergranular corrosion.

The main features of Thermanit H 347 Si wire electrodes include:

Stabilization by niobium: Improves resistance to intergranular corrosion, especially at high temperatures.

Increased silicon content:Provides additional protection against oxidation and improves weldability.

Excellent corrosion resistance:Suitable for applications exposed to corrosive media.< /p>

Good welding properties: Enable stable and clean weld seams with good flowability of the weld pool and minimal spatter formation.

In summary, Thermanit H 347 Si wire electrodes offer a reliable solution for demanding welding tasks , where resistance to intergranular corrosion and mechanical resilience are required. They are ideal for applications in the chemical industry, power plant construction and other areas exposed to high temperatures and corrosive conditions.
