Exhaust valve for CNG
Exhaust valve for CNG
(OP)
i have chemical composition on the valve material as follow:
C=10.06 ; Mn=2.12 ; Fe=50.91 ; Ni=5.27 ; Cu=1.37 ; Si=0.37; Cr=20.56.
How i can know this result is approximately to which std material?

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Unless your calibrations samples closely bracket this chemistry you could easily have more than 15% relative error on each element.
There are Cu bearing variants of 300 and 200 series stainless alloys, but given the obvious error in C the Cu could be surface as well.
