Alloy Steel Armor Plate AR500 yog ib hom tshwj xeeb ntawm cov pa roj carbon steel phaj uas tau raug alloyed kom muaj zog thiab hnav tsis kam, ua rau nws zoo tagnrho rau cov ntawv thov kev tiv thaiv ballistic. Paub txog nws lub zog siab thiab ua haujlwm ntev, AR500 tshwj xeeb yog tsim los tiv thaiv kev cuam tshuam thiab kev nkag mus los ntawm qhov projectiles xws li mos txwv thiab shrapnel.
Cov pa roj carbon steel feem ntau yog siv los ua cov khoom siv hauv cov cuab yeej cuab tam vim lawv cov khoom siv zoo heev thiab kev lag luam. Thaum alloyed nrog cov ntsiab lus ntxiv xws li chromium thiab molybdenum, carbon hlau tuaj yeem hloov mus rau AR500 armor daim hlau, muab kev tiv thaiv zoo tshaj plaws.
Cov txheej txheem alloying txhim khu lub hardness thiab toughness ntawm cov pa roj carbon steel daim hlau, uas muaj peev xwm tiv thaiv tau ntau yam ballistic hem. AR500 armor daim hlau yog tsim rau kev siv tub rog thiab kev ruaj ntseg, tsheb armoring, lub cev armor thiab structural reinforcement qhov twg ballistic kuj tseem ceeb heev.
