Dear Dng, Polynomial conversion is the easiest way for doing it, but I have found a better one: HV = 7091,843768 / (125,6010596- HRB) HV = 1974914,439/ (102,9783872- HRC)2 ---------- 20 < HRC < 40 HV = 15936,2268 / (79,13859914– HRC) ---------- HRC > 40...

renting prize thank you very much for the information. I have already finished the investigation and I am doing the quote. I want to take in count all the expenses and I vave been trying to find how much costs to rent a vickers and rockwell hardness testers. I have sendt some e-mails to...

I need the formula Sorry did not express correctly. The aim of my project is to find the formula that links vickers and rockwell (example: HR=a(HV)^2+b(HV)+c). I have done tests using steel Which goes from HV170 to HV900. My question is: How can I get that formula using the values I got in my...

I am doing my university project about the relation between vickers and rockwell hardness. I know that there is not a mathematical relation but I need to find a good approximation. I have practice both tests in more than 50 specimens (HV70-HV950) and I have more than 300 (HV1,HR1),(HV2,HR2)...
