Carbon Free Steel ( commercially pure iron ) - really is THIS soft

You know things are messed up when your trouser trumpet gets harder than the rebar in your apartment building :D

I did get handed a bar of commercially pure iron and it was say 20mm in diameter, and it was as soft as lead.... I absolutely shit you not. Hence all the alloying and heat treatments etc.. BUT commercially pure iron, is actually very hard to come across, because you can't use it for anything.... I have ONLY ever come across ONE bar of it... 20mm in diameter and perhaps a meter or so long... So when you get the OLD black and white Superman movies - with him bending the prison call bars open, it's either lead or pure iron....

Leader Desslock - Consuming Content, does not have the same value or credibility as Creating Content. I found a video on ALL the shitty concrete projects in most of China - like there are 10 story apartment blocks made from this SHIT - full of people.... Traumatised at the thought..... but out of that 28 minute video.... this was the ONE section that I wanted to show other people - because unless you have handed commercially pure iron products, or seen it being bent by hand etc., you would NOT believe how soft it really is..... So I edited out ONLY that ONE bit, then saved it as a file, and then uploaded it so everyone else can see it too... So I am glad that you found it educational and entertaining. BUT - I'd really like to see you making GOOD, USEFUL and INTERESTING content.
