[sarane613]

I am looking for equivalent following materials. I have only the French norm (AFNOR). Of course I will accept any norm.
90MCV8
40CMD8

Thanks in advance

90MCV8 is now called 90MnCrV8 according to DIN EN ISO 4957. It is equivalent to the North American tool steel Type O2 (UNS T31502) according to ASTM A 681.

40CMD8 is similar to the North American tool steel Type P20 (UNS T51620) according to ASTM A 681. Both of these are commonly used tool steels, and therefore widely available.
