300 series stainless stress relieve
300 series stainless stress relieve
(OP)
low temperture stress relieving of 300 series stainless steel is recommended not to exceed 775 deg F. I have a fabrication that is recommended to stress relieve. Any recommendations on time in furnace, max. insert temperature and max allowable removal temperature from furnace.
Thanks
Thanks





RE: 300 series stainless stress relieve
I doubt that the 775 deg F stress relief temperature is going to do much good. What is the reason for requiring this? Regarding maximum allowable removal temperature, this is 775 deg F, the time at temperature depends on thickness, I would use 30 minutes.
RE: 300 series stainless stress relieve
Stress relieving 300 series s.s at 775F will only remove the peak stresses and aid in dimensional stability. The stress removal process is really slow at this low temp., one source recommended that the soak time be 4 hrs per inch.
