Hardox

hello,

i have recently heard about hardox being used with great success on robots such as TAN and dantomkia and was wondering what information you people could provide on it?

i do know thats its a type of steel wearplate and is heavier than stainless but thats about it.

One of its most interesting features is that it actually gets harder when beaten and is quite sturdy. But that is also the trouble: it is very difficult to cut (we use watercutting, lucky for us there is a company in Belgium who can do that), even more difficult to bend (where is that very very big press ?), quite heavy and you need special things to weld it with (not the ordinary welding sticks !). Mario will give more details this afternoon when he is back from work but this is what I could tell you now.

Notice that Supernova did not damage the armour of Mechaniac in the Worldchampionships. Helmut humbly confessed that it was the bolts holding the armour to the frame that gave way. Strategically placed, like on the back of the Dutch robot Pullverizer where Razer couldnt cut through (!!!) in last years Worldchampionships, it is very interesting.

I am now using Hardox 400 at 4mm thick in preference to grade 2 ti,cutting isnt a prob
it will bandsaw with work!and plasma cuts easily

well we use it on our cutters and for next year well only have to sharpen them slightly with an angle grinder

i wont tell u wot kind of punishment we put them through though

seeing Ian Lewiss face light up when he tried to bend a 3mm thick piece was interesting... wonder what that means?

A hernia?

hes a big girl..

Mario told me my explanation was good enough so he wouldnt add to it. I notice however that I forgot to mention one last thing: when you weld Hardox it becomes weaker at the welding spots. Slightly weaker.
It is hell for your drills and eats angle grinder plates by the kilos but it is still quite interesting to use.

Heres my unqualified or put in.....
Is Hardox heavier than its equivelent thickness in steel plate? And doesnt harder usually mean more brittle?

It is heavier than steel but it is not brittle. That is the most fascinating quality of Hardox: it only gets harder and harder with each blow. But not brittle.
