Annealing temperature for 446SS

[timsch]

I'm looking for the annealing temperature of SA-276 446SS. The Mechanical Requirements table shows this material to be in Condition A, which is annealed, but Table 3 does not list 446 specifically or generically. Where is the annealing information?

Typical annealing temperature for 446 stainless steel is 1500 deg F to 1650 deg F.

Thanks. Was this information in the ASME BPVC or elsewhere?

The annealing temperature is available from various reputable web sites.

The min annealing temp is usually in the applicable material specification.
Since SA-276 doesn't say then go to producers literature.
We would adjust the temp based on actual C content, but 1550F is a good starting point.

Thanks Ed. Can you elaborate on adjusting the temp based on C content?
