Bulletproof steel plate is generally used in bulletproof protection and explosion-proof projects, such as range equipment, bulletproof doors, bulletproof helmets, bulletproof vests, bulletproof shields; bank counters, confidential safe; riot vehicles, bulletproof cash carriers, range equipment, armored personnel carriers, combat vehicles, submarines, landing boats, anti-smuggling boats, helicopters, etc.

At present, bulletproof steel plate can be divided into two categories: one is hot-rolled steel plate. In addition to good bulletproof function, this kind of steel plate has good process ability, weld ability and cold bending performance, and its tensile strength is more than 900 MPa, generally less than 1000 MPa The other is heat-treated steel plate, which is quenched by heat treatment after hot rolling to meet the strength requirements, with high strength, usually more than 1500 MPa, but the processing performance, weld ability and cold bending performance are far inferior to hot-rolled steel plate.

The manufacturing method of bulletproof steel plate is characterized by obtaining high strength and high toughness by quenching and tempering, and reducing the strength of hot rolled coil by bell type annealing after normal hot rolling, which is conducive to later uncoiling and shaping, and then maintaining good shape by pressure quenching. The manufacturing process of hot-rolled bulletproof steel plate mainly includes: hot metal pretreatment → converter smelting → LF refining → RH refining → continuous casting → heating → hot continuous rolling → controlled cooling → coiling → sampling → function inspection → packaging and delivery → delivery; and the heat-treated steel plate is de-coiled on this basis → cutting plate → heat treatment → sampling and inspection of performance → packaging and warehousing → delivery.

Usages of Bulletproof Steel Plates

Bulletproof protection, bulletproof steel plate is generally used in bulletproof and explosion-proof projects, such as bulletproof door, bulletproof helmet, bulletproof vest, bulletproof shield; bank counter, confidential safe; riot car, bulletproof cash carrier, armored personnel carrier, combat vehicle, submarine, landing boat, anti-smuggling boat, helicopter, etc.

FY2200 the armor plate has four characteristics

1. Careful design of alloy composition: low alloy micro alloying makes the performance to the extreme and has the best process performance.

2. Refining raw materials: repeatedly refining inside and outside the furnace; frying harmful gases and impurities to the minimum; welding and cold bending.

3. Accurate hot rolled plate shape: minimum thickness tolerance; maximum two-way flatness.

4. Self-controlled spray quenching: the microstructure is fine and the hardness distribution is uniform.
