What is the minimum carbide solution treatment temperature for 300 series stainless steel.
Thanks in advance for your time.

RE: What is minimum carbide solution treatment temperature
However, I want to caution you that you should review the material specification heat treatment requirements for the particular grade of stainless, period.
RE: What is minimum carbide solution treatment temperature
The time will have a lot to do with your part size and shape, your furnace, and how heavy the prior carbide formation is.

RE: What is minimum carbide solution treatment temperature
Suppose you start with carbide solution treated bar (treated above 1950F), then hot or cold forge fasteners per A-193 Gr. B8. Per the A-193 Spec., after forging the fasteners shall be carbide solution treated (ref. A-193-'08 para. 7.3.3).
We started off with carbide solution treated material so the question is, ARE there carbides that need to be treated and if so, at what temperature? If there ARE NO carbides that need to be treated due to the original starting condition, at what temperature can I perform the carbide solution treatment?
FYI, we will be performing an A-262 intergranular corrosion test after all heat treats.
Thanks again.
RE: What is minimum carbide solution treatment temperature
The carbide solution treatment should be repeated for maximum corrosion resistance after hot or cold forming for this Class of material. I would re-solution heat treat at 1950 deg F min.
RE: What is minimum carbide solution treatment temperature
If the parts have been hot formed then you need to go back to 1950F min for full solution.
