Plasma cutting AR 500 Steel

[KHK]

Does anyone have any experience cutting AR 500 steel?
This seams familiar to me but the search does not show anything.

ar-400 is common hard plate, ar-500 is just a little more dense.... plasma will cut it, but it wont be pretty.... it likes to be flame cut the best..... kinda funny, you would think that a plasma would cut it the best, but experience proves otherwise... keep a very tight torch tip and keep it even, stay slow and steady and allow the puddle time to form otherwise you will be "chasing" the old cut... will be good experience for ya

its hard and abrasive, should be around 50rc.. i would think if your cutting relatively thin stuff you should be ok, like 1/4"...

if they are planning on machining it afterwards, you'll need to leave a fair amount of stock per side so they can get through the crust as the crust will probably be hard as a brick probably..

i remember them preheating and welding, then covering with blankets and slow cooling...

i use to work at a place that rebuilt buckets for endloaders and dozers, they used this stuff.. AR= abrasion resistant
