LY Steel has developed the FD series with tensile strengths ranging from 900MPa to 2200MPa and the ArmaPro series with Brinell hardness levels from 450 to 700 for protective applications. LY Steel's protective steel offers excellent bulletproof performance, cold-forming properties, and weldability, making it widely applicable for private bulletproof vehicles, bank cash transport vehicles, armored personnel carriers, training ranges, and anti-terrorism vehicles. LY Steel's hot-rolled LG900FD has successfully passed certification by the Ministry of Public Security and is now used in cash transport vehicles. The heat-treated bulletproof steels ArmaPro500 and ArmaPro550 have passed inspections by the China Ordnance Equipment Research Institute, meeting NATO testing requirements.
