What is HR15N hardness?
HR15N – This method is known as “Rockwell 15N.” A relatively light, 15 kgf load is applied to case hardened parts treated to achieve a minimum effective case depth 0.007 inches or a total case of 0.012 inches.

What is Rockwell 15N?
Rockwell Superficial Hardness 15N-Scale. Superficial Brale indenter, 15 kgf load. Symbol: HR-15N. The Rockwell Hardness Test presses a steel or diamond hemisphere-conical penetrator against a test specimen and measures the resulting indentation depth as a gage of the specimen hardness.
What is the bulk modulus of iron?
The Bulk Modulus – resistance to uniform compression – for some common metals and alloys.
| Material | Bulk Modulus – K – | |
|---|---|---|
| (106 psi) | (GPa) | |
| Copper | 17.9 | 123 |
| Iron, cast | 8.4 – 15.5 | 58 – 107 |
| Iron, malleable | 17.2 | 119 |
When to use conversion of hardness test values?
1.12 Conversion of hardness values should be used only when it is impossible to test the material under the conditions specified, and when conversion is made it should be done with discretion and under controlled conditions. Each type of hardness test is subject to certain errors, but if precautions are
How do I convert HV to GPA?
To convert HV to GPa multiply by 0.009807. To use the conversion calculator simply enter a number value into the desired field and click calculate. All results shown will be equivalent values. Values are given to four significant figures (the odd result may show 9’s or 0’s over running).
Why does G-Wizard include a hardness conversion calculator?
Our G-Wizard Calculator software includes a hardness conversion calculator because it has a full set of hardness conversion charts and a calculator built right in on the “Quick Refs” tab: Hardness conversion calculator for Rockwell, Brinell, Vickers, Shore Scleroscope, and Tensile Strength…
How do I convert hardness from one unit to another?
The Hardness Conversion Calculator is particularly handy. Enter a from value, select the from units, enter the “to” units, and G-Wizard will give you a value (if there is one) in the new hardness units. Here’s a closeup of the unit selector:
