hardox 400 thickness range for bulletproof walls
Q345 is a steel material. It is a low alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, HARDOX 400 thickness range welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
Due to vast experience & concerted efforts of all employees, we are known as a reliable supplier of API 5l Line Pipe, seamless pipes and ERW pipes.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick HARDOX 400 thickness range steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.
Between alloy wear-resistant layer and the substrate of wear-resistant steel is metallurgically bonded. Through special equipment and automatic welding process, high-hardness self-shielding alloy welding wire is uniformly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the compounding process, due to the different alloy shrinkage ratio, uniform transverse cracks occur. It is a distinctive feature of wear-resistant steel plates, HARDOX 400 thickness range.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
