Welcome to BBN High Strength Steels Factory
Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.
GJB/1496A-2000 this standard uses and manufactures 28Cr2Mo steel plates with thicknesses of 10, 12, 15, 20, 25, 30mm for armored vehicles, and 26SiMnMo steel plates with thicknesses of 5, 6, 8, 10, 12, 15, 20mm and thicknesses. 28Cr2Mo is armored bullet-proof steel, code-named GY4. It is the main protective device on the tank. It needs to have high elasticity resistance. It also needs to have good processing technology and welding performance to meet the requirements of the tank manufacturing industry.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the S690QL plate steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The mode of iron and S690QL plate steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of S690QL plate steel logistics.
We are engaged in S690QL plate corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, S690QL plate ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.
