What does E-300 mean in the passivation
process?
+++
I have a customer who wants his stainless steel parts finished and
to Passivate
Mil-F-14072 [link is to spec at TechStreet] -E300. But
the customer is under the impression that a E-300 spec. identifies
the surface finish, and the previous parts that were purchased had a
surface finish of #32 in them, but the drawing clearly does not
specify this. What is the E-300 refering to?
Thanks,

E300 IS THE CODE FINISH UNDER MIL-F-14072. WHEN YOU LOOK FURTHER
IT GOES TO PASSIVATE PER ASTM
A380 [link is to spec at TechStreet]. NONE OF THESE
CODES HAS ANYTHING TO DO WITH A 32 FINISH.
