Description

UF-S is a neutral agglomerated chromium compensating flux. It is intended for automatic and semi-automatic welding of stainless, corrosion-resistant and heat-resistant steels with suitable welding wires and for arc strip cladding.

The flux is designed for direct current welding of single-pass seams without limiting the thickness of the parts to be welded. It shows good welding and technological characteristics.

It is used in the chemical and petrochemical industries, for pressure vessels, storage facilities and containers for chemical products, in solving problems of the energy and nuclear industries, the pulp and paper industry, civil engineering, transport engineering, etc.
