BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of Ramor 300 bulletproof steel steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main Ramor 300 bulletproof steel production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Whose hardness is higher between No.20 steel and No.45 steel, Ramor 300 bulletproof steel? Both No.20 steel and No.45 steel belong to high-quality carbon structural steel. According to the characteristics of high-quality carbon structural steel, its carbon content determines the performance of the steel. The higher the carbon content, the higher the hardness and strength of the steel, the lower the plasticity and toughness. The carbon content of No.20 steel and No.45 steel are 0.20% and 0.45% respectively, which shows that the hardness of No.45 steel is higher under the same process.

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel Ramor 300 bulletproof steel surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

S355J2 steel plate 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 Ramor 300 bulletproof steel rolling speed is 1.6-2.0m/s, the 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℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of Ramor 300 bulletproof steel steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. Ramor 300 bulletproof steel, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
