22SiMn2TiB is a military steel, 22SiMn2TiB code 616, 22SiMn2TiB (616) is a tank armored bulletproof steel plate. It is ultra-high strength steel with welded heat affected zone corrosion resistance.
Four properties of 22SiMn2TiB(616) steel plate:
22SiMn2TiB steel mechanical properties: strength, hardness, plasticity, fatigue, impact toughness.
22SiMn2TiB steel chemical properties: corrosion resistance, high temperature oxidation.
22SiMn2TiB steel physical properties: density, melting point, thermal expansion, magnetic properties, electrical conductivity.
22SiMn2TiB steel process performance: cutting performance, forgeability, castability, weldability.
From the late 1960s to the early 1970s, F-6 bulletproof plates were developed for railway special trains, 616 (22SiMn2TiB) thin armored bulletproof steel plates for infantry fighting vehicles, and 681 bulletproof steel plates for bulletproof cars. On this basis, an armored plate with 616 (22SiMn2TiB) as a substrate and a jujube-shaped chrome corundum ball was developed, which achieved the effect of reducing the weight of the chariot and improving the mobility under the premise of the same ballistic resistance.
