QUESTION: When people talk about bearing and wear resistant materials they refer to the materials PV value.
Do you know what reported value on the materials data sheet is known as the materials PV value?



Hi Richard,
The PV value refers to the pressure/velocity factor of a material and because most of this type of materials have additives which give them their own unique characteristics it is not possible to single out one reported value from a materials data sheet.
Data sheets are simple ways of showing a materials basic characteristics so that they can easily be compared with other grades of the same type of material.
They are generalist in nature, if you wish to know a materials properties and its suitability for a purpose or how to process the material to get the best results it is better to discuss these facts with the supplier directly most have some technical knowledge source that can help.

Thank you for your question sorry I could not help further.
kind regards,
