Applicable materials, indenters, and conversion precautions for three hardness test methods.

- Brinell (HBW): Large indenter and large indentation, suitable for castings, forgings, and thicker materials; good representativeness.
- Rockwell (HRB/HRC): Fast and simple, suitable for batch inspection; use HRB or superficial Rockwell for thin sheets.
- Vickers (HV): Small indentation, suitable for thin sheets, surface-hardened layers, and small areas; can measure gradients.

Notes:
- Conversion between different hardness systems is not an exact relationship; for important applications, the test method should be specified in the contract.
- Stainless steel thin sheets commonly use HV or HRB.
- Specimen surface roughness and thickness affect the results.
