First thing is to give some indication of where in the world you are.

As far as I can tell, NC6 is a Polish steel specification and does not seem to have an equivalent AISI designation. Unless you are in Poland, you might be better searching for it as 1.2063 or 145Cr6.

Edit: Or maybe Bohler K505.
