It all depends dude...What are you looking for?

Depends on the metal used. Big difference between cold rolled and true armor plate.

.0001" of Adamantium will do it.
Link Posted: 7/30/2009 5:57:44 PM EST
i don't know the answer, but it will zip right through 3/8" astm a36 structural steel like its butter...no matter what projectile you're using.

To stop one shot?

more than 1/4 inch and less than 1/2 in.


That's my wild ass guess from shooting a lot of shit with my guns.

i have seen it penetrate some thick stuff. all depends on the metal. how thick for mild steel plate?

yep between 3/8 and 1/2 inch of normal old carbon steel.

But it takes .0087" of Unobtainium to do it, too.

90 degree impact?

1/4 titanium nitride.

It's more of s metallic cement or ceramic though.

They will be cheaper to buy than manufacture.

Or you'll end up with plates that are 35lbs + each.

Please don't do this.

If you do, you also have to flute your AR barrel with a dremel.



Yeah, don't do that either.

Don't know if this helps or not, but I have seen it rip right through old car rims... at the thickest point. FMJ's though, not soft or hollow-point.

I shot the flange of an old "I" beam with my .223. The flange is 3/8" thick. The .223 fmj didn't fully penetrate and left a large dimple on the back side of the flange. My BIL shot the same flange with his .308 and punched it nicely.

I shot a 1/2" piece of lab grade titanium with a 7mm Magnum and it made a large hole through and through. The piece was semi supported and the distance was about 20 feet.

O_P needs to do a box o truth on 1/4 inch steel backed with a kevlar vest.

That would be cool to see it the vest would stop it after the plate.

Link Posted: 7/30/2009 6:12:07 PM EST
3/8 to 1/2 of a500, a550, or a600 would stop the rounds but you may end up being shreaded by the spalling or injured by blunt force trama. there are other factors to consider. not to mention the stuff weighs a ton.

At 8' the lead will spit right through 1"

But the jacket coming back will leave a scar.

Not all steel is created equal. Some grades are harder than others.

I was just wondering if there was a super duper metal that would stop it and didn't weigh a ton. I think I'll pass now.

Ive shot M193 at 1/2" of mild plate at 100yds, and it penetrated all but about 1/16th inch, dimpling the bottom of the hole.

Already been said but it's cheaper to buy than make unless you have a source for free hardened metal.
If you want to stop 5.56 you'll probably want to go with a different material, steel has to be pretty thick to stop the higher velocity stuff.

If you just want to fill your carrier with metal plates as cheap as possible check out EGI for $100 each

Won't stop 5.56 at close range but it will probably do a better job than what you can find in a scrap yard.

'cause, you know, the government is just keeping all this high strength, superlightweight steel underwraps and all.

I hear they've got steel so light, it floats! I drove to the lake myself with my car that runs on water, man!

I shoot floor tile alot and its hell on .223. 2 of them turned a XM193 into dust. I bet one infront of a 1/4" would do it.

3 1/4" tiles stopped a round of .308 ball. That one shocked me.

Stopping bullets isn't about hardness. It's about redirection and dispersion of energy. Most wearable armors use materials that allow the bullet to deform and spread the impact region over an increased area, which reduces the concentration of energy at any given point. This is why they use ceramics which powder and Kevlar which flexes.

it's much like the high school physics project of saving an egg dropped from a height. You want the "saving" device to absorb the impact energy.

make sure its sewed in there good. A falling plate could take you junk clean off. Or worse it might scratch the logo off glock.

I get your point.... however - harder steels DO stop bullets better than mild steels, and therefore can be much thinner, and lighter, due to this. There is no denying that. However, any AR500 plate will still pale in comparison to a ceramic plate by weight.... which is why they are not used.

So, if you make your own, you are going to test it, right? I want pics of this.

Hint: don't wear it while testing.

But the downside is that AR500 steel can handle multiple strikes without damage and ceramic sacrifices itself to stop the bullet allowing another one to penetrate. You are sacrificing durability for weight savings which can be either a lifesaver if one needs to move faster or a death dealer if more then one round impacts in the same area.

Never shot steel of any appreciable thickness, but I do know that a "2 thick aluminum block will stop .5.56 just fine although it blows a BIG crater in it.

DIY plates with floor tiles epoxied to a 1/4" aluminum/titanium or 1/8" steel face plate?
