Hardness converters translate between different material hardness scales: Rockwell, Brinell, Vickers, Shore, and others.
Trinn-for-trinn guide
- 1Rockwell: A, B, C scales (different indenters, loads)
- 2Brinell: BHN (ball indenter), larger impression
- 3Vickers: Very hard materials, diamond indenter, small load
Løste eksempler
Inndata
Steel 50 HRC (Rockwell C)
Resultat
Approximately 475 HV (Vickers), 450 HB (Brinell)
Approximate conversions
Vanlige feil å unngå
- ✕Treating conversions as exact (they're approximations)
- ✕Using wrong scale for material (Rockwell inappropriate for very soft/hard materials)
Ofte stilte spørsmål
Which hardness scale is most reliable?
Vickers most precise for hard materials, Brinell for softer. Different scales measure different things.
Does hardness relate to tensile strength?
Generally yes, but not directly. Hardness and strength both measure resistance to deformation differently.
