Brinell to Vickers
Type a value in HB to get it in HV instantly.
392HV
That's 1.96× as hard as 304 stainless steel, while spring steel is 1.14× harder.
Convert the other way: HV to HB
What it means
How hard is that?
For carbon and alloy steels (ASTM E140). Conversions between scales are approximate; for other metals and for exact values, test on the scale you need.
The math
How to convert HB to HV
Hardness scales convert by table (ASTM E140): HRC 50 = 513 HV = 481 HB, HRC 40 = 392 HV = 371 HB. Tensile strength ≈ 3.45 × HB MPa.
Example: 371 HB = 392 HV.
