I need advice on whether or not a material I am thinking of using would be appropriate for the job. I need to make some pins for a Powerlifting combo rack. I am thinking about using ETD 150. Would that material be sufficient for the job?

This is the part

This is the material I am thinking of using: https://www.onealsteel.com/alloy-steel-bar-cd-etd-150.html

This is where the part is on the rack,


This is the rack itself,


The main gray tube is 2.5x2.5 .125 wall mild steel and the adjustable black tube is 2x2 .125 wall mild steel.

Thank you for any help. I really appreciate it.
