Picked up some Chrome Moly tube 1.5 x .120 wall roll bar material but it has no makings that state such....can anyone read this stuff?  Markings on the tube.1 1/2 ODO 120 amt (B or 8) 01415 USA OCTOJ 525 80 5sp I have searched the web but cannot translate this...thanks for the help. Some things can't be carried in a tool bucket.
Reply:You might see if you can have someone do a hardness test on it.  Chrome moly is 4130, mild steel is 1018.  You can do a search for steel properties to get an idea of what steel you've got after you know the hardness.America Needs AMERICA'S Oil!!!"Global warming is the greatest scam in history ...There is no run away climate change.

Reply:try calling your local supplier.  ask them what the numbers are for CM.  Or go down and tell them you have 1 1/2 ODO 120 amt (B or 8) 01415 USA OCTOJ 525 80 5sp  and looking to get a price quote for more.I am tired of Ketchup, I want the Gravy...
Reply:looked in the D1.1 and none of those numbers jive with anything in table 3.1... don't know what those #'s mean, is it DOM? those numbers might just be something with manufacturing? .... nothing in tab 1.2 in the D1.3 either...?
Reply:Dom for sure, thanks for the help. Will do a search localy for a hardness test........Some things can't be carried in a tool bucket.
