I can't afford a $400 bar, but I SURE can't afford to have a bar that isn't strong enough! I had a rep from Ivanko online, and here is our conversation:
FamilyMan: While I have you online, I have a question about these bars.
FamilyMan:I have a Olympic bar that came with my 300# set. It has worked for a while, but I have outgrown it. I got up to 500# Squat, and ran out of weight -that is all the weight I had in the house.
FamilyMan: I read the article Ivanko about bars breaking (How to Break an Olympic Bar), and it made me start to wonder about our bar. My wife has grounded me from lifting over about 300# until I get a better bar.
Ivankoweights: bars w/ stress cracks or hydrogen embrittlement can snap w/o warning
FamilyMan: Right that is really funny. I emember that illustration about the Russian dude doing the snatch and having the broken bar cut through his jugular. Yikes!
Ivankoweights: worst case scenario
FamilyMan: What kind of limits do you think an Ivanko OB 28KG or OB-Econo might have?
ivankoweights: the ob econo is a 65,000 psi bar
ivankoweights: the ob -28 is an 85,000 psi bar
ivankoweights: your bar is probably 45,000 psi maybe
FamilyMan: OK, does the psi thing translate into pounds?
ivankoweights: not really
ivankoweights: because is the 500 Ib rating static or dynamic?
ivankoweights: how dynamic?
ivankweights: see what I mean
FamilyMan: Yep. How can I tell what kind of bar to get for my lifting needs?
vankoweights: how much force is subjected to a bar when it is at yield
ivankoweights: how far can it yield before it wont return to perfect straightness
FamilyMan: OK, I guess I'll just get my handy psi meter out and measure...
