The Development and Application Research of Light Weight Heat Treated C-grade Bullet Proof Steel
The Light weight heat treated C-grade bullet proof steel was developed through composition design and optimization based on multiplex alloying, multiplex micro-alloying design ideas and complex phase structure strengthening theory.The puzzle how to avoid the quenching deformation problem of super high strength thin sheet was solved through heat treatment in die with a suit of cooling system.Such C-grade bullet proof steel plate has fine tempered lath martensite structure and has a higher strength than production which is made by a Inc.in Sweden.The shooting and certification test results show that the shot resistance of C-grade bullet proof steel plate can met the protection demand of the Protection specification for cash carrying vehicles(GA164-2005)standard.Comparison with C-grade bullet proof steel plate made by a Inc.in Sweden, the developed C-grade bullet proof steel plate can degrease 5 to 10% weight under the same shot resistance condition.It will be in favour of lightweight for cash truck and anti-hijacking vehicle and energy conservation and emission reduction.
