Ar 400

[Johnch]

This afternoon I made a trip to the scrap yard
I wanted some steel plate for a new bullet trap
As I wanted a Bullet Trap for short range plinking in the back yard

I got more than I needed
But one of chunk of steel I got was labeled AR 400

It is 1/2" thick and it is more than large enough for the deflector plate I want for the new bullet trap
Sides and bottom will be 1/4" , as that was what I could find in a usable size

I will be cutting all the steel plate with a water jet cutter
As it is great to just let the water jet cutter do all the work and not need to use the torch

But I have never used AR 400
Any problems with cutting it with the water jet cutter ?


Thanks
John

It's just water quenched carbon steel plate really. It has good abrasion and impact wear. Cuts, grinds & welds same as plain old A36 plate.

I am glad

I just had some 1/4” and 3/8” AR 500 water jet cut (old reactive targets being repurposed into protectors for pistol target stands). It cut easily, leaving a pretty clean edge even using a fast cutting rate, and including 1/4” holes for bolts.

We used AR plate to make silhouettes.
If I remember correctly it began cracking pretty bad from the impact of the bullets.
T1 steel was must more resistant to cracking.
AR = Abrasion Resistant.

That reminds me I need to get busy and build a trap been putting it off thanks.

AR 400 is not very tough. A rifle bullet will do damage to the plate unless you angle it at least 45 degrees of more.
The club I run thought AR500 was the way to go but the targets failed and were severely damaged after just a few matches. We have since gone to AR550 and they still show impact damage or crack from hundreds of shots on them.
