Dear Sirs,

We have our extrusion dies nitrided at job heat-treters.
We would like to control the nitriding quality of incoming dies.
How can the quality of nitriding of an aluminium extrusion die is evaluated?
What should be the case hardness and depth? Some other criteria?
Please also e-mail your reply to my mailbox at
