It is designed for shear blades, extrusion rams, tampers, ripper, teeth and coal planes. It is used for the repair ana production of cutting tools, particularly for building - up cutting edges and working surfaces. The deposit is highly resistant to friction corrosion and impact. The production of new tools by using non-alloy and low-alloy base metals is also possible. The weld metal deposit is equivalent to a high speed steel with increased Mo-content.
