Description
Cobalt-based rod
The full grade 12 rod develops high hardness, abrasion resistance, and good corrosion resistance. These properties make this rod the ideal choice for saw blades for wood and bars, as well as for industrial cutting applications for carpets, plastics, paper, and the chemical industry. Non-forgeable and can be worked with difficulty using carbide tools. It bonds well with weldable steels of all grades, including stainless steel.
