Transversal Charpy test on 1026 tube before and after stress relieve
Transversal Charpy test on 1026 tube before and after stress relieve
(OP)
Hi!
I would like to know if a stress relieve should affect the result of a charpy test on tubing. (my tube is 1026 11" OD x 2" wall).
I've sent my tube to a firm for a charpy test on hot rolled 1026 tube. My results were 12 ft·lb/in longitudinal and 14 ft·lb/in transversal.
I need to get a better charpy test with that material, is it something possible?
Anyone have data or experiences about that? I've searched a lot through internet but didn't found anything.
Thanks,
JP

But you are limited by the original chemistry.
I have seen this fight more than once.

Thank you for the follow up info. What you have discovered is what you have been told; improvements can be achieved through normalizing.
I trust that the absorbed energy is now acceptable.
You can also specify toughness requirements in the P.O. to your materials supplier. Better to do that than hope that the material will meet as yet unspecified requirements.

Also, this is a plain carbon steel tube in 2" wall thickness. You're not going to have equivalent properties through this thickness.
