4340 tensile strenght
4340 tensile strenght
(OP)
I am very new in this domain. We are in the motorsport business and recently we started to design and produce rollcages. I have a few questions for the people who really know about steel properties.
We are working on a very light rollcage from 4340 alloy but I discovered that it has lower impact strength than 4130 and a lot higher tensile strength. I want to ask you what should be the right alloy for this application, considering that the rollcage is only useful in case of an impact.
Thank you in advance.

The supplier is telling me that his products comply with ASTM A519 and I must decide if I want the tube normalized or stress relieved.
As far as I know, normalizing can soften/harden/stress relieve the steel so I dont know what he means. The cage will be treated for stress relief after welding, anyway.
Any help would be appreciated.

I suggest you download the following .pdf files and familiarize yourself with the different tube manufacturing processes:
