HARDNESS

Table hardness

To compare different methods of measuring hardness, Dominial has a hardness comparison table available for you.

We can send these to you at your request.

Nitrate hardnesses

When nitrating the treatment does not so much determine the hardness, but more the type of material.

For example, the final hardnesses differ with the same nitrating treatment.

To gain insight into which material gets which hardness during nitration, we have a table available for this.
