| Well I hope that you fellow ORHTF folks could help me out on my steel target design. I'm looking creating my own steel target at the steel fabrication shop where I work. I'm interested in using Hardox 500 1/2" plate as the target, is the AR500 plates I see online similar to the Hardox 500? Largest gun I have to shoot at the steel would be my 300 RUM (and of course .223, 6mm, .308, etc). Looking to fire off rounds at a minimum distance of 200 yards. Planning on making the plate on a static mount angled at 12 degrees. The place I work at has no knowledge about creating steel targets so I'm looking forward to see what fellow ARFCOM members chime in with. |

As far as I can tell Hardox is a "metric" measurement. I use that term because it seems European and it's not rockwelll or Brinell. I also hate places that measure their charpy tests in Joules rather than ft/lbs.
Long story short, it's late, I've had a few beers and shooting this steel at 200 yards should be fine. |

Well...Daniel is right (had to do that)...
I too looked at the material data sheet. Here and see that the indended use is for "wear resistance". The hardness is 500 HBW which converts to a Rockwell C of about 50 (maybe depending on actual test equipt)...pretty hard stuff, as is should be for wear resistance. May be brittle so lets be scientific about this: Go shoot a piece of it and report back. |

Isn't AR500 a trade name? You can compare your plate properties to it. Some have recommended using AR400 if welding is needed. Either way insure inside corners have a radius to prevent cracking. Yes, as is Hardox. I just bought some and it came with ASC painted on the plates http://www.associatedsteel.com/products-wearplates-500bhn.shtml |
