Annealing 316 During Heat Treatment
Annealing 316 During Heat Treatment
(OP)
Hi all,
Just a quick question. I have a component that is friction stir welded 316SS and 1060 plain carbon steel. We'd like to Austemper the 1060 component, but I'm wondering if this will have any affect on the hardness/corrosion resistant properties of the 316 part? Induction hardening is not an option due to cost. The 316SS component has undergone quite a bit of cold working and is around 35HRC. I'm wondering if the austempering process will anneal the 316 component appreciably?

Then you will not need to worry about sensitization.
Make a sample part.
You can test resulting weld strength, distortion of the the SS, softening of the SS (it will often).
You also need to do micros and corrosion tests of the 316 near the welds. You should be looking for sensitization and the formation of detrimental intermetallic compounds.

Due to different thermal expansion of different material , distortion will occur. The weld med with mixed material will respond in a different way than both parent metal ( may be more metalic carbides).

Distortion is the biggest problem that I would worry about.
