Very aggressive and robust brush that is able to withstand high mechanical loads. Perfect for heavy-duty brushing in pipeline and container construction.

In addition to brushes with a stainless steel filament, PFERD also offers brushes of the INOX-TOTAL type for work on stainless steel (INOX). It is particularly well suited to use in critical environments.

In order to fulfill the requirements for brushing stainless steel (INOX), PFERD produces all stainless steel (INOX) brushes using 302 stainless steel wire. Practical experience gained from industrial use confirms that this wire quality achieves excellent corrosion resistance with optimum brush life. The wire found in stainless steel (INOX) brushes tends to become magnetic after cold working. All PFERD brush products with stainless steel wire (INOX) are color-coded blue in the Tool Manual. All of these brushes are recommended for use on all stainless steels (INOX), such as 316. The reason for this is a change in the microstructure caused by deformation (e.g. during the wire drawing process). This does not have any impact on the quality and corrosion resistance of the INOX filament. The filament is still resistant to corrosion.

Stainless steel wire (INOX) is temperature-resistant up to 850 °F.
