Affect of temperature on Steel
Affect of temperature on Steel
(OP)
I have an application where a 316 stainlesss part is being used to maintain a compressive load on an assembly. During manufacturing, the SS part was heated to a point where the part relaxed and no long maintained a load on the assembly.
My question is at what temperature will the steel become adversely affected by the heat? Will it begin to relax prior to the annealing temperature since it is loaded? I did a some digging and it seems to be common practice to heat steels (to temps lower than the annealing temp) to aid in forming processes. I would view heating a part that is under load to be somewhat analogous.
In the end, I need to set a maximum allowable temperature for the process.
Thanks.

So, if you can limit the temperature to 300 deg F or less, and the tensile stress applied to maintain the compressive loading does not exceed the yield stregnth of the stainless, you should be ok.
