In Reply to: Conversion from knoop to vickers hardness posted by Mike on November 26, 2003 at 10:39:12:
: Hello,
: I'm looking for an extended conversion scale from knoop hardness to vickers hardness, especially for the range of 920 Hk and up.
: Can anybody help me with that, or guide me to where I can find this?
Hi Mike
You will need to be careful here. General conversions above this level are not reliable. Factors such as material type and test load have a significant effect. The only reliable way is to formulate the conversions by actually comparing the hardness results from your specific material type.
