Ok some people get free or nearly free. Many people have to buy but sometimes prices vary greatly.If you don't get a bargain just buy known steel and little bit costly but you also learned more that can be repeated. Thanks good job
No real way to guess at the alloy. Most rebar for the past 30 years is just random pieces of old ship chopped up on a beach in India or Bangladash and rerolled in a makeshift workshop.
Did you preheat the oil? because most oil hardening 'tool' steals prefer being quenched in 80° Celsius oil. Like the O1 tool steel or W-Nr. 1.2510 in Europe.
Rebar is mostly recycled steel, I’m told so it’ll be an unknowable mix I believe? The large diameter is normally higher quality used for DOT and larger structures thus the grade is specified in contract specifications.
Looks like a fine grain pattern on that thick bar
..Good series of test Lee. i asked a supplier what was the makeup of some rebar once, he replied, steel...
Thats a good answer haha

I agree completely I forgot to mention that I wouldn't pay for rebar it's just not good enough steel, but its worth using if its free

yes I pre heat with a hot piece of junk steel I don't check the temp after though.

So your large "Rebar" is really dewy Dag thread when smaller ironworkers use them to "tack" bolt holes, iv seen them in large posts used as anchors
I wondered what it was I knew it wasn't rebar but didn't know the name thank you!!
Your moma could be case hardened : /
Ever think about diat ... hrmm ... didja ... hrmm 😮
