Analysis of fault layer problem of 6mm FB2 bulletproof steel

Since it was established in 2000. Based on the domestic rich 6mm FB2 bulletproof steel product resources and the great steel demand of the international market, our 6mm FB2 bulletproof steel service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

Cold rolling steel is made of hot rolled coil under recrystallization temperature at room temperature. Cold rolled steel sheet is produced by cold rolling process, which is called cold plate. The thickness of 6mm FB2 bulletproof steel, cold rolled sheet is generally between 0.1 mm and 8.0 mm. The thickness and width of cold rolled sheet produced by most factories are less than 4.5 mm. The thickness and width of cold rolled sheet are determined according to the equipment capacity of each factory and market demand.

The main difference between 6mm FB2 bulletproof steel, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of 6mm FB2 bulletproof steel, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

The hardness of 6mm FB2 bulletproof steel, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.

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.
