Can anybody please tell me what the difference is between Z 1 NCDU 25.20 and Z 2 NCDU 25.20?

Thanks
 
The 1 and the 2 are the average Carbon content times 100.
 
Z 2 NCDU 25.20 is AFNOR name for 904L (AISI) or 1.4539

In AFNOR code, Z stands for stainless steel. First number stands for percentage of carbon x 100 (i.e. 10 means 0.1% of Carbon)

here we have less than 0.02% for Z2 and less than 0.01% for Z1
