Who here knows how level three steel plates are manufactured? I was thinking about how makeshift armor could be produced in the event of some sort of incident that would make purchasing one impossible and I thought to myself, hey why not ask the hivemind? I would assume the process is simple for a person familier with metallurgy.Just as a sidenote, I have no intention of making my own armor, plates are cheap and it sounds like a darwin award in the making for someone who is unfamilier with the process. I am just curious as to how it is done. |

I may be wrong. This is from Pinnacle's website. Ballistic Resistant Steel Armor Plate Our ballistic grade steel is mostly compared to either Mil-A-46100 and/or Mil-A-46177 armor plate for its ballistic defeating properties and is used in a wide variety of armoring applications. Test plates from each heat lot of material are subjected to stringent ballistic testing before being qualified and approved for use. The manufacturing facility for our ballistic grade steel is approved to Mil-I-45208A. Specified Mil-A-12560 CL.I., steel plate is also available, Mil-A-46100 steel is available up to 6" inches in nominal thickness. Mil-A-12560 CL.I., is available up to 22" inches in nominal thickness. Our ballistic grade steels are offered with variable toughness, hardness and workable chemical properties, dependent upon usage requirements. Our standard MIL-A-46100 ballistic grade steels are offered in six basic levels of protection. Speciality grade high hardness and wrought homogenous steel are also available. Threat Level NIJ III-A/UL-3 Special NIJ III/UL-4 UL5 & 8 UL7 & 8 NIJ IV Weight (Lb./Sq. Ft.) 4.8 7.66 10.2 12.76 15.31 20.42 Thickness .1188" .1875" .250" .3125" .375" .500" www.pinnaclearmor.com/transport-armor/armors.php |

Here you go. I WAS wrong. Though the civilian armor may not be to these specifications. www.eng-tips.com/viewthread.cfm?qid=159941&page=1 |
