Hardox AR 500 damage.
- Thread starter hunta
- Start date
I've been quoted, and seen in reading a 3000fps limit for Hardox 500. However I can't find evidence for this or if this is 3000 muzzle velocity or at the target. This might be an issue as a lot of loading for non lead suggests 3000fps to get expansion
I've found papers on testing Hardox at quite short ranges and my take is that the 3000 fps should be at the target, not the firing point at the target. (eg High Performance and Optimum Design of Structures and Materials II)
So with normal stalking rounds at 200m there really isn't an issue as bullets will be doing under 3000fps and impact probably below 4000J which seems to be the limit
Has anyone better data please?

I had a square cut from hardox 450 from a tipper body 60gr poly tipped varmints no problem 55gr sierras holed looked like it was drilled 100yrd from a 22-250 took it back to the guy that gave it to me and he said thats impossible although he had the evidence in his hand i never did try the 6.5 swede
Use a hard facing rod as that is what they are meant for 7018 under it if its a thick plate . Its the speed but also the Chinese junk we import into the UK is like i say junk and its getting worse melt by melt !
A target that will swing freely helps

I once condemned £7m of mooring equipment (shackles, rings, etc) brought in from China with genuine certificates of conformity from a well-known classification society, speedily followed by a T45 destroyer’s anchor chain cable set. Took one of the Ketner shackles from that set up to Solid Swivel in the Midlands and load tested it - it went at one third of the rated load! The 3 parts of the shackle were then subject to metallurgical examination which confirmed they were from 3 very different melts, contrary to specifications. Absolute rubbish!

A friend who worked for a crane and lifting equipment company passed similar comments some years ago. Apparently his firm were sceptical of Chinese chains and shackles being supplied and the claims being made for strength and their light weight in comparison to traditional suppliers. His firm submitted samples for test and the chains were found to be extremely brittle.
I’m interested to see results,
