Welded hard surfacing KALMETALL pipes

The KALMETALL brand designates a range of hard-faced steel systems comprising a tough basic shell with hard-face welding. The basic material of the systems is the reinforcement substrate. It consists of standard steels, depending on the specific application.

The hard-face welding forms the wear layer. It consists of a C-Cr-Fe system with primary chromium carbides. This provides the extreme hardness of the hard-face weld, which can be up to 820 HV, depending on the alloy composition. The standard thickness of the hard-face welding ranges up to 4 mm. Special thicknesses over 4 mm up to 18 mm are also available on request.
