What kind of steel are crow bars made of? Is it 4140 or 1018? What makes them so strong to where they dont break or fatigue when you pull on them? They are hardened but is it case hardened or tempered? Are all bars made from the same material? (Flat bar vs. big crow bar) What is there breaking strength is it measured in tensil or grade like a bolt?
Look forward to hearing what you can teach me.
Thanks,Cory
