Steel EN10025-2 S355JR Plate heavy plate boiler steel

The company celebrates Hong Kong-Zhuhai-Macao Bridge Opening. In October 23th, 2018, Chinese President Xi Jinping announced the opening of the Hong Kong-Zhuhai-Macao Bridge (HZMB) in Zhuhai, South China’s Guangdong Province. The HZMB is a 55-kilometre (34 mi) bridge–tunnel system consisting of a series of Steel EN10025-2 S355JR Plate three cable-stayed bridges, an undersea tunnel, and four artificial islands. Hong Kong-Zhuhai-Macao Bridge is the world’s longest sea-crossing bridge connecting Hong Kong, Macao, and Zhuhai—three major cities on the Pearl River Delta.

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.

The toughness index of Q345B steel should be tested by impact test at 20 ℃. Although the strength of Q345B steel and Q345A steel are the same, the S / P control of Q345B steel is more strict, and the ambient temperatures of Steel EN10025-2 S355JR Plate, Q345B steel and Q345A steel are different. The cold impact test refers to the impact test at a certain temperature to obtain the energy consumed by punching the specimen. The more energy consumed, the higher the toughness of the material. Q345A is not subject to impact test. So Q345B steel is better than Q345A steel.

In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our Steel EN10025-2 S355JR Plate quality. Till now, we keep exporting around 100 tons per month as regularly.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our Steel EN10025-2 S355JR Plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

10CrMo9-10 seamless pipe implements European standard EN 10216-2. The chemical composition of 10CrMo9-10 seamless pipe: C 0.08-0.14, Si ≤ 0.50, Mn 0.30-0.70, P ≤ 0.025, S ≤ 0.020, Cr 2.00-2.50, Ni ≤ 0.30, Mo 0.90-1.10, Al ≤ 0.04, Cu ≤ 0.03. The mechanical properties of 10CrMo9-10 seamless pipe: tensile strength: 450-530 MPa, yield strength: ≥ 280 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. Steel EN10025-2 S355JR Plate, 10CrMo9-10 seamless pipe is a kind of high temperature and high pressure boiler steel, which is mainly used in the production of power station boiler, steam boiler equipment, pressure vessel, large pressure pipe, etc.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, Steel EN10025-2 S355JR Plate, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.
