What Are the Benefits of High Speed Cobalt?
There are many great reasons to consider using a cobalt steel alloy. These are some of the key characteristics of these alloys:
Superior Red Hardness: The addition of cobalt can bring the Rockwell hardness up to 70 Min. Notably, these alloys perform especially well at high heats, maintaining their hardness and usability in production environments.
Heat and Abrasion Resistance: Similarly, high speed cobalt tends to perform very well in terms of heat and abrasion resistance. These characteristics are the main reasons why people choose high speed steel. With the improvements of cobalt steel, the advantages are only compounded.
Shorter Cycles: The above characteristics add up to one very important practical benefit: shorter cycle times. Tools made with these alloys can be run longer with less maintenance. That means cost savings for industrial applications.
