Export great hardox 500 machinability to Romania

SM490B steel, HARDOX 500 machinability is a kind of low carbon welded structural steel. With this low carbon equivalent, it can produce good cold forming properties. SM490B steel plate is usually supplied in hot rolling or controlled rolling delivery conditions. The SM490B is commonly used in the engineering and construction industries. It has high yield and tensile strength, and provides a variety of processing and testing options to make it highly available in your construction projects.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, HARDOX 500 machinability based on a high starting point and high technology, the company has vigorously developed various steel products HARDOX 500 machinability and deep-processed parts, steel structures, precision castings, seamless pipes.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled HARDOX 500 machinability products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the HARDOX 500 machinability rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and HARDOX 500 machinability pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
