Convert Rockwell C hardness to indicative Vickers and Brinell values for early stainless steel comparisons.
Technical reference
Calculation basis and limits
Hardness scales are not perfectly linear. Alloy, heat treatment, test method and standard can change the relationship. Use this page for screening and quotation preparation.
Confirm the grade, standard, application conditions and supplier documentation before making a final engineering or purchasing decision.
Calculation method
Formula and worked example
Hardness Conversion Calculator formula
Use the stated inputs and units to calculate an indicative result.
Worked example
At 30 HRC, the indicative interpolation is about 286 HV and 270 HB. The ordered material certificate remains the controlling record.
