What is the value of BP300 bulletproof steel yield strength

The steel grades BP300 bulletproof steel of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of BP300 bulletproof steel steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.

20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than BP300 bulletproof steel, No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as BP300 bulletproof steel, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.

S355J2 steel plate BP300 bulletproof steel rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the BP300 bulletproof steel single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
