BBN hardox 450 vs ar450 angle steel bar stock

The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team. In the future service process, the after-sales service adopts regular return visit for customers. Timely understand the customer's satisfaction with our products, and solve the user's problems at any time.

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, Hardox 450 vs ar450 tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of Hardox 450 vs ar450 steel and 542,000 tons of steel.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. Hardox 450 vs ar450, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

We have strong strength of steel plate production, high-quality products, and low prices. Guarantee to thank the new and old customers for their trust with good products, excellent quality, low price and perfect service. The company provides customers with professional "one-stop" logistics services: warehousing, loading and unloading, and transporting. The perfect logistics management, facilities, network and guarantee system guarantee customers' worry-free delivery.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the Hardox 450 vs ar450 steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of Hardox 450 vs ar450 seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
