SA240 409 S/S spec change
SA240 409 S/S spec change
(OP)
Hi,
The latest version of SA240 now specifies that 409 S/S is obsolete and replaced with 40910, 40920 or 40930. The differences between them being different amounts of Ti and Cb. The mill can provide either of these standards when 409 S/S is order under the A240 specification.
Has anyone investigated the benefits offered by the different types. I suspect benefits are in formability and corrosion resistance.
Thanks,

Let's just say that I am a skeptic, since swearing would be very unprofessional.
Stabilized 409 is good, how they do it really doesn't matter.

Corrosion, every where, all the time.
Manage it or it will manage you.
