Key smelting points to ensure the successful production of armor stanag 4569 1 steel bulletproof

Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of armor STANAG 4569 1 steel bulletproof capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the armor STANAG 4569 1 steel bulletproof overall strength, competitiveness and anti risk ability of the company.

15CrMo alloy plate is a pearlite structure heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature, and armor STANAG 4569 1 steel bulletproof has certain hydrogen corrosion resistance. Due to the high content of Cr, C and other alloy elements in 15CrMo alloy plate, the steel has obvious hardening tendency and poor weldability. The weight calculation formula of 15CrMo alloy plate: length × width × thickness × 0.00785 = kg / m. Delivery status of 15CrMo alloy plate: hot rolling, controlled rolling, normalizing, high temperature tempering, QT, etc.

NM400 wear plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery and other product parts. Such as excavator, loader, bulldozer bucket plate, blade, side blade, crusher liner, etc.. NM400 wear plate is also commonly used as high-strength structural steel with yield strength ≥ 800MPa. The main function of NM400 wear plate is to provide protection in places or parts where wear resistance is required, so as to prolong the service life of the equipment.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the armor STANAG 4569 1 steel bulletproof plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. armor STANAG 4569 1 steel bulletproof, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
