Convert Rockwell C hardness into approximate Brinell, Vickers, tensile strength, and superficial Rockwell values. Use it when comparing material specs, heat treat data, and machining charts.
Let our engineers find the right factory for your specs. 100% Quality Guaranteed.

No. HRC, HB, and HV are measured differently, so conversions are approximate and vary by material family and heat treatment.
Yes. Harder materials generally need lower cutting speeds, more rigid setups, and more conservative chip loads.
HRC is common for hardened steels, HB for softer steels and cast irons, and HV for thin coatings or microhardness checks.
Use this converter when a drawing, heat treat certificate, or cutting chart uses a different hardness scale than your shop reference.
