Hot rolled hardox 500 density main application
Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing. Under such condition, our technician department can provide technical support in time, anylize customer design or make drawing according to customer needs rapidly, so that we can proceed smoothly. The profession of our team has won great praise of customers.
S890 steel is a quenched and tempered high-strength steel plate, the series grades are S890Q, S890QL, S890QL1. S890Q, S890QL, S890QL1 steel,HARDOX 500 density plates, where S means structural steel, Q means that the impact temperature of the steel plate is -20°C, and QL means that the impact temperature of the steel plate is -50°C. Then guess what QL1 stands for. QL1 means that the impact temperature of the steel plate is -60°C, and 890 means that the thickness is £50mm.
A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The HARDOX 500 density, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.
20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than HARDOX 500 density, No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as HARDOX 500 density, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.
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.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For HARDOX 500 density ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the HARDOX 500 density standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
