Valve Seat Material

[JPD]

Can anyone tell me the standard relating to the following valve seat materials:

CN10CU
MS20CU

Maybe these are a specific supplier mateial code.

These may be internal spec designations. If they are tied to any ISO, SAE, ASTM-type standards, they should be listed in the body of the spec somewhere. Contact the manufacturer to get more specifics.
