Hello,
I need to reveal the austenitetic grain sizes of the 60SiCr7 spring steel material.
I have tried picral, nital, viella's and something more that doesnt have specific names.
But non of them has worked.
Is there anyone who has worked with this material before.
Am I using wrong etchants, or can I be doing wrong about the time or the temperature.
